Abstract. Students' study time and academic performance can reflect their learning status. This
study investigates the relationship between study time and academic performance by analyzing the
number of selected courses, study time, and grades provided by open-source data sites. The effect
of study time on academic performance was studied using linear regression. Studies have observed
a positive relationship between study time and academic performance. When the study time reaches
a certain standard, the grade will no longer show a significant change. This paper can assess
students' learning status and help them plan their study time reasonably.

1. Introduction
1.1 Background
Nowadays, people have been increasingly competitive since their student days due to the vast
population base when they apply for a higher-level school or better job. According to a survey of
more than 200 employers by the American Association of Colleges and Employers, 67% of
companies said they screen candidates by GPA (Davies & Hammack, 2005), which can reflect the
importance of academic success on future careers. In order to achieve success, students not only have
to use the appropriate skills, but also put in a lot of effort. Effort is central to strategy use which, in
turn, results in improved academic performance (Meltzer, 2001). The effort can be reflected by the
engagement of students in school and the levels of engagement can be estimated from the amount of
time spent on academics (Ed, 1992).
Learning takes time and curricula are designed to provide students with opportunities to learn
during classes and during time for self-study (Genesee, 2000). It is generally considered that, as more
time is spent on learning, performance will be better. At the same time, students are full of confusion
about their future career development during the student period. They may spend time on their
hobbies to find future goals which could make them balanced the time allocation between hobbies
and learning, resulting in problems such as grade decline due to unreasonable time allocation. Issues
with school performance can lead to more problems, such as family conflicts or loss of interest on
learning. The research shows that the social and emotional climate of family relationships is adversely
affected by poor school performance; at the same time, family atmosphere is a mediating, factors
problems which may result from school failure (Hurrelmann et al., 1988).
Whether the investment of study time is related to academic performance is a controversial issue.
One the one hand, the research shows that academic performance has a positive relationship with the
study time, and students with low performance especially increase their performances with increased
study time (Spitzer, 2022). In this article, based on his conclusions, analyzing the further impact as
the study time keeps increasing, trying to find the limitation of the time investment.
On the other hand, some people have an Opposite view on this conclusion. The total time students
spent working during a given week did not directly affect academic performance (Sarath, 2006). The
conclusion may be led by the method he collected samples. Distributing surveys to students may not
feel comfortable providing answers that present themselves in an unfavorable manner. Also, since
students may have different foundations in high schools, the result could be inaccurate.
All in all, this research will analyze the relationship between study time and academic performance
based on the data collected from two Portuguese secondary schools. The marginal contribution of
research lies in that school reports and questionnaires are used simultaneously to avoid some research

biases. Then, the grades of Portuguese can objectively test the students’ academic performances, since
the investment of student time will have more pronounced feedback on grades.
1.2 Literature Review
The SWQ's current field size shows that academic issues are the biggest concern for students, even
more so than finances and health (Davey et al., 2021). Does the longer you study, the better your
grades will get? This research problem may be concerned by many scholars and students.
In addition, further testing the impact of different educational methods on students' learning
efficiency can help teachers discover the suitable educational methods for their students.
For students, self-awareness about study time means self-control of study state, and can compare
their study state with others, to understand and adjust their study methods and better plan study time.
Finally, this can make them no longer be confused about learning, increase their enthusiasm for
learning and reduce their anxiety about learning. By leveling the study efficiency, it would lead to
good grades.
1.3 Main Contents
This study aims to study the relationship between study time and academic performance. This
research will be answered in following questions: (1) Whether the study time will affect the students’
academic performance? (2) If it is, how does study time affect academic performance?
2. Data and Method
2.1 Data Source
Data for this study came from a survey in two Portuguese schools. The data includes student grades,
demographic, social and school related features by using school reports and questionnaires. The
dataset received questionnaires from 651 students. 386 of them are female students and 265 of them
are male students.
2.2 Measures
The academic performance of a student can be reflected by the grades of the student which was
discussed in this research. In this case, firstly, students' performance was measured by the test in a
subject: Portuguese language (por). The grade of the test was out of 20.
Secondly, the study time was measured by 1-4 scale (1 = less than two hours of study time per
week, 2 = 2 to 5 hours of study time per week, 3 = 3 and 4 = 5 to 10 hours and more than 10 hours).
For each set, 20 students were chosen (10 boys and 10 girls) which are used to control variables, and
to facilitate and find patterns.
2.3 Method
The primary method of the study is called linear regression. By plotting the study time of each
student and its corresponding grades. The linear regression model aims to find the best fit line of the
plot diagram. The best fit line is relating to the formula y= mx +c. For this study, the variable X
represents the students’ study time and Y represents the Portuguese grades. m and c are the gradient
and constant values defining the straight line. To compute the linear regression, the approach
introduced is called the least-square method which minimizes the squared difference between the
actual data points and a straight line. In this case, the values of m and c seeked is to minimize the
squared difference SD.

3. Result
From the Figure 1, it can be seen that there's a positive linear relationship between the time
investment on study and students’ grades which can indicate the more study time, the better academic
performance. However, there's a limitation which can be seen from the Figure 1. When the study time
reaches 3 (5-10 hours), the student's grade has no significant change compared with 4 (over time
hours). As we see from Table 2, the coefficient of variable X is 1.87 which also indicates the positive
relation between X and Y.
4. Discussion
Study time was recognized as an important factor for students’ grade. Students need different
levels of effort based on their knowledge difficulty, learning ability, and career goals. Firstly, students
should invest the necessary study time if they want to get better grade. Secondly, academic
performance does not need to make further requirements on the amount of study time, and the main
point is to improve the learning skills. For example, they can make good use of the time and find
suitable learning methods. Otherwise, it will not make much difference no matter the time invested
more or less. Students should not blindly pursue the length of learning time, but should focus on the
learning quality in each hour. Reasonable improvement of study efficiency can not only save learning
time, but also allow students to have extra time to explore extracurricular interests. All in all, it is
essential to spend enough time, but it is even more critical to get learning benefits during this period.

Kesitsel bir tasarım kullanılan çalışmada 719 lise son sınıf öğrencisine (Ortyaş = 17.71) ulaşılmıştır. Veri toplama araçları olarak Sınav Kaygısı Ölçeği ile demografik bilgi ölçeği uygulanmıştır. Ayrıca düzenleyicilik rolünü araştırmak üzere katılımcıların en son girdikleri deneme sınavından aldıkları puanlar ve son altı ayda kaç dakika ders çalıştıkları ile ilgili bilgiler toplanmıştır. Verilerin analizinde SPSS programı kullanılırken, düzenleyicilik ilişkisini test etmek amacıyla Process Macro model 1 kullanılmıştır. Sonuçlar, ders çalışmaya ayrılan süre ile sınav başarısı arasında pozitif yönde ilişki olduğunu ve bu ilişkinin sınav kaygısı tarafından düzenlendiğini göstermektedir. Ders çalışma süresi ile sınav başarısı arasındaki bu pozitif ilişki sınav kaygısı düşük olanlarda daha yüksektir. Sınav kaygısı yüksek olan adayların daha az ders çalışma süresi olduğu ve bu durumun da dolaylı olarak sınav başarısını etkilediği görülmektedir. Elde edilen sonuçlar ışığında üniversiteye hazırlanan adayların, zaman yönetimi becerileri, kaygı ile baş etme becerilerine yönelik stratejiler tartışılmış ve literatür ışığında adaylara, öğretmenlere, anne-babalara ve ileride bu konuda yapılabilecek araştırmalar ile ilgili önerilerde bulunulmuştur. Abstract: This study examines the moderator role of test anxiety in the relationship study time and exam success was examined. The reserachers of the study with a cross-sectional design reached 719 high school students (Mage = 17.71). Test Anxiety Scale and demographic information scale were used as data collection tools. In addition, to investigate the moderator role, additional information was collected on participants' scores on the last practice exam they took and the number of minutes they studied in the last six months. While SPSS program was used in the analysis of the data, Process Macro model 1 was used to test the moderator role. The results show that there is a positive relationship between time spent studying and exam success, and that this relationship is regulated by exam anxiety. This positive relationship between study time and exam success is stronger for individuals with low test anxiety. It can be seen that candidates with high test anxiety spend less time to study which has an indirect effect on test success. In the light of the results obtained, strategies for time management and coping skills for candidates preparing for university were discussed. Suggestions were made for candidates, teachers, parents and future research on this topic in the light of the literature.

Background & objective: It’s no secret that medical students have access to a plethora of medical literature, which can make it challenging to determine the right sources and how to cover them effectively using various study habits and strategies. Our objective was to determine the association of study habits (time and location), study duration, study strategies, and study sources with academic performance. Methods: It was a cross-sectional study conducted in six Medical Colleges in Peshawar, Pakistan between 13th April 2023 to 13th Jun 2023. Total 138 students were selected for the study. A well-structured questionnaire was used for data collection. Participants were from both genders and in both public and private sector medical colleges. First-year students and students from medical colleges outside of Peshawar were excluded from the study. SPSS (Version 20.0) was used for data analysis. Results: The study revealed that daily study hours (during normal days), residence status, library study, morning study timings, active recall, MCQS solving, and watching online videos made a significant association with academic performance (P < 0.05). Pearson’s correlation showed a positive and statistically significant association between daily study hours (during normal days), study strategies, and academic performance (p < 0.05). The multiple regression model explained 30.5% of the variance in academic performance. Conclusion: This study established a noteworthy link between academic performance and various factors, including daily study hours, strategies, and specific study sources. Notably, morning study sessions, active recall, MCQs-based strategies, and online video resources showed significant associations with enhanced academic performance. doi: https://doi.org/10.12669/pjms.40.11.9502 How to cite this: Osama M, Saeed A, Raza ul Haq M, Baseer MA.

Aims: to explore the time that crammer start to study and the time of exam being held and relate this two with the result of the remedial exams which conducted electronically (computer based). Study Design: simple descriptive cross sectional study Place and Duration of Study: conducted during January to February 2024 in the faculty of Medicine, Universitas Kristen Indonesia, Jakarta-Indonesia. Sample: respondents who join the remedial exam during 2022. Methodology: electronic questionnaire regarding time to start studying being distributed prior the exam/test. Sufficient explanation regarding the research is given before consent is politely requested to each exam's participant. Data obtained from questionnaire were combined with demography data (gender, place of residence) and the result of the exam. Results: Cramming conducted by 69.7% of our respondents, with the involvement of male student is more common compared to female student and regarding their place of residence, more student that live in their own house with their family do the cramming. Most of the perpetrator started studying at 20.00-24.00 pm. Students passing rate in this study were low. Female students score better when they did not cram while only male students who conduct cramming and still fail the exam get a slightly higher mean score than male students who fail the exam and did not cram. Female students got a slightly higher mean score than male students. Conclusion: Cramming is risk taking like gambling behavior. It can give negative impact to the perpetrator's mental health. The phenomenon of cramming is quite common, especially among male student, but the passing rate was poor. Cramming mostly started late at night. Male students who fail the exam tend to get higher grades if they cramming while on the other hand our female student tend to get higher score in they did not cram.

Background: Assessing grit among pharmacy students provides insights into the students' experiences as well as the importance of implementing interventions to increase their levels of grit. The purpose of this study was to assess students' grit in Nigerian pharmacy schools and to identify factors that predict the amount of grit among pharmacy students. Methods: This study utilised a nine-item questionnaire-based cross-sectional design among final-year pharmacy students from one public university, in each of the six geopolitical zones of Nigeria for a month. Descriptive and inferential statistics were employed. Results: A total of 590 pharmacy students responded to the questionnaire (response rate = 66.89%). Most students 409 (69.32%) were between the ages of 20 - 25 years. A majority, 573 (97.1%) reported being free from any chronic diseases and 427 (72.37%) reported being engaged in extracurricular activities. A group mean grit score of 37.091 ± 0.253 was observed. Students from all the schools reported ‘Not Like me’ 14 (2.37%) to ‘I have overcome setbacks to conquer an important challenge’, while 275 (46.61%) chose ‘Very much like me’. Predictors of high grit level were institution (Beta, p-value), mode of accommodation (ꞵ = 1.494, p = .039), and sponsorship (ꞵ = 4.207, p = .047). Conclusion: Pharmacy students in Nigeria have a high grit level and the institution of study had an impact on the level of grit.

Learning strategies, emotional intelligence, and academic performance have been proposed as variables with great impacts on language learning processes, which can be reinforced in distance university education. In this educational modality, learning is completely autonomous and independent, which implies the need to develop particular skills that make it possible to take advantage of previously provided learning experiences and resources. This chapter reports a study on the relationships between learning strategies, emotional intelligence, and academic performance in a course of English 3. Data were collected from a sample of 132 students in distance education at a university in Spain. For the analysis of the variables, a non-experimental design was used, making use of descriptive and correlational statistics. The results showed a high average rating on the learning strategies scales, as well as adequate understanding and emotional regulation in the students, in contrast to emotional perception, a dimension that obtained a low average rating.

As the cornerstone of spatial geometry and engineering drawings, three‐view drawing lays the necessary foundation for students to learn geography, graphics, industrial design, geographic information science, and so forth. However, teaching three‐view drawing can be challenging due to its abstraction. Currently, desktop and handheld augmented reality (AR) systems are widely applied to three‐view teaching. However, existing systems suffer from visuo‐tactile inconsistency and contain unfriendly interactions, resulting in a poor learning experience. In this paper, head‐mounted AR is introduced for the first time in the teaching of three‐view drawing. A system was designed for learning three‐view drawing to facilitate students' free exploration and learning in lessons. Additionally, a comparative experiment was designed and conducted to investigate whether multimodal interaction and head‐mounted AR help students to better understand the relationship between concrete three‐dimensional (3D) objects and abstract two‐dimensional planes and the impact on subjective perceptions. The results demonstrated that the proposed system significantly improved learning performance. Furthermore, the proposed system heightened students' interest in learning, made reproducing 3D structures more intuitive, and students were more willing to use such systems in their future studies.

Background The frequency and severity of mental health problems in student populations have been a growing cause for concern worldwide, and studies have identified measures of a number of mental health symptoms that have been steadily increasing in frequency and intensity over the past 20–25 years. Methods In two studies we investigate the levels and domains of pathological worrying in university student participants. Study 1 is a retrospective study of Penn State Worry Questionnaire (PSWQ) data collected between 2001 and 2019. Study 2 describes the development of the Student Worry Questionnaire, a short and easily delivered measure of student worrying that identifies both frequency of worry as well as the student-relevant domains across which worrying occurs. Results Study 1 revealed a steady increase in student worry scores of around 20% between 2001 and 2019, with a significant positive correlation between year of data collection and mean PSWQ score. The domain scores in Study 2 indicated that academic work was a significantly higher worry than any of the other domains, and worries about intimate relationships and ‘what people think of me’ were also worries that scored higher than either financial or health worries. Conclusions The present studies indicate that pathological worrying can be added to the list of anxiety- and stress-related symptoms that have been shown to be on the increase in student populations in recent decades, and we discuss whether these increases represent a greater willingness to report symptoms or a genuine increase in experienced symptoms over time.

Decades of research produced inconsistent findings on whether study time can lead to achievement gains in mathematics. Data generated by more than six thousand students from three different countries who solved more than 1.1 million problem sets using a dedicated mathematics software are analyzed regarding the effect of study time on students' achievements in mathematics. Results showed that more study time led to higher performance scores in mathematics. Further analyses revealed that low-performing students in the first school year (2017-2018) who increased their study time in the following year (2018-2019) revealed greatest gains in performance in the same school year (2018-2019) and even in the year after (2019-2020). Finally, results replicated previous observations of robust performance scores within students over the three school years, with performance scores in 2017-2018 predicting those of 2018-2019 which predicted those of 2019-2020. These results support the idea that students, in particular low-performing students, can boost their academic abilities to upper levels when increasing their study time.

Today's college students are less prepared for college-level work than their predecessors. Once they get to college, they tend to spend fewer hours studying while spending more hours working, some even full time (D. T. Smart, C. A. Kelley, & J. S. Conant, 1999). In this study, the authors examined the effect of both time spent studying and time spent working on academic performance. The authors further evaluated the interaction of motivation and ability with study time and its effect on academic performance. The results suggested that nonability variables like motivation and study time significantly interact with ability to influence academic performance. Contrary to popular belief, the amount of time spent studying or at work had no direct influence on academic performance. The authors also addressed implications and direction for future research.

This study was designed to examine academic selfperceptions in adolescents with learning disabilities as part of a two-year intervention project. The major objective was to compare students' perceptions with their teachers' judgments of their level of effort, strategy use, and academic performance in reading, writing, spelling, and math. The sample consisted of 308 students with learning disabilities, 355 average achievers, and their 57 teachers. Findings indicated that the students with learning disabilities viewed themselves as motivated, hard-working, appropriately strategic, and academically competent, thus reflecting positive academic self-concepts. Teachers' judgments were significantly more negative and they rated the overall group of students with learning disabilities as below average in their strategy use, academic performance, and organization. The most interesting finding occurred when the results were analyzed for students whose overall academic achievement was in the high-average range. Teachers rated the effort and strategy use of students with and without learning disabilities as above average, indicating that their perceptions were influenced by students' academic success and were not negatively impacted by the existence of a learning disability. In contrast, teachers judged low-achieving students with learning disabilities more negatively than their low-achieving peers without learning disabilities. Thus, teachers' perceptions of students' effort and strategy use were influenced by students' academic success and their learning disabilities did not interfere negatively with this perception. Lastly, findings indicated that hard work, in combination with efficient strategy use, can lead to success in the classroom.

The present study examines the effect of three different structured methods, traditional, independent and problem‐solving, of teaching children arithmetic in the beginning of 7th grade in Sweden, age 13 years. The progress made by these students is presented by measures of their arithmetic ability, calculation and quantitative concept, as well as their self‐regulated learning skills in mathematics, characterised as internal and instrumental motivation, self‐concept and anxiety. The results will be discussed with reference to a socio‐cultural perspective. This study has a split‐plot factorial design with time as within‐subject and type of intervention as a between‐subject factor. The results show that there are no significant differences between teaching methods when assessing arithmetic in total and calculation. Students’ progress in quantitative concepts is significantly better if teachers teach traditionally or with a problem‐based curriculum. In order to develop aspects of self‐regulating learning skills, the results show that pupils would benefit in a traditional or problem‐solving curriculum. Problem‐solving seems to be more effective than traditional and independent work for students’ internal motivation. Traditional work and problem‐solving are more effective than independent work for students’ self‐concept.
