Evidence-Based Time Management and Study Planning Strategies for Students
Published:
In brief
Research on learning and time management points to a small set of strategies that actually help: spacing study sessions over time, testing yourself instead of rereading, and blocking fixed, timed study periods such as 25-minute Pomodoro sessions. Popular habits like highlighting and rereading notes show low benefit in controlled studies, while self-quizzing and spaced practice consistently improve recall.
Two different bodies of research inform how students can plan their time and study more effectively: cognitive psychology studies on which learning techniques actually improve memory, and surveys that measure how time-management habits relate to grades. Neither field offers a single formula, but both point to specific, testable practices.
What research says actually helps you learn
A widely cited review coordinated by psychologist John Dunlosky and colleagues, published through the Association for Psychological Science, examined ten study techniques commonly used by students, including rereading, highlighting, summarization, and practice testing. The review found that practice testing (quizzing yourself) and distributed practice (spacing study sessions apart instead of cramming) received the highest utility ratings, because both consistently improved performance across different ages, subjects, and types of tests.
By contrast, five techniques received low utility ratings, including rereading, highlighting or underlining text, and summarizing material — despite being among the most common study habits students report using.
I was shocked that some strategies that students use a lot — such as rereading and highlighting — seem to provide minimal benefits.

Study techniques by research utility rating (Dunlosky et al. review, APS)
Technique
Utility rating
How to apply it
Practice testing
High
Self-quiz with flashcards, past exam questions, or blank-page recall before checking notes
Distributed (spaced) practice
High
Spread review of the same material across several days or weeks instead of one long session
Rereading notes or textbooks
Low
Limited benefit on its own; pair with active recall instead
Highlighting / underlining
Low
Limited benefit; marking text does not require retrieving it from memory
Summarization
Low
Can help organize material but showed weaker effects on retention in the review
Structuring study time: the Pomodoro method
One widely used time-blocking method is the Pomodoro Technique, created by Francesco Cirillo in the late 1980s while he was a university student struggling to focus, according to a breakdown of the method by productivity app Todoist. Cirillo used a tomato-shaped kitchen timer (pomodoro is Italian for tomato) to set a fixed period of focused work.
The technique works in four steps: set a timer for 25 minutes and work on a single task without interruption; when the timer rings, mark the session complete and note what was finished; take a 5-minute break; after four completed sessions, take a longer break of 15 to 30 minutes. Todoist notes the interval length can be adjusted, but the core idea is using a fixed, uninterrupted block to reduce procrastination and self-interruption.
Does time management actually change grades?
A cross-sectional study of 390 medicine, dentistry, and pharmacy students at the University of Sharjah in the United Arab Emirates, conducted between February 2016 and March 2017 and published in a peer-reviewed journal indexed on PubMed Central, measured time-management ability with an 18-item questionnaire and compared it to grade point average (GPA). Most students, 71.5%, scored in the moderate range on the time-management scale, 15.6% scored high, and 12% scored low. The study reported a very strong positive correlation between time-management scores and GPA, but the authors themselves cautioned that the unusually high correlation likely reflected limited variation in GPA within their specific student sample rather than a universal effect size.
The study also found no significant link between time-management scores and gender, prior school background, or year of study, and noted a significant difference between medical and pharmacy students, with medical students scoring higher on the time-management measure.
A practical weekly planning sequence
List every deadline, exam, and assignment for the term on a single calendar or planner so nothing is tracked only in memory.
Break large assignments into smaller tasks with your own interim deadlines, rather than one deadline at the end.
Block fixed study periods into a weekly schedule before other commitments fill the time.
Use timed focus blocks, such as 25-minute Pomodoro sessions with 5-minute breaks and a longer break after four sessions, to structure each study period.
Within each subject, replace rereading with active recall: close the notes and try to reproduce or explain the material, then check accuracy.
Spread review of the same topic across multiple days instead of concentrating it into one sitting, consistent with the high utility rating for distributed practice.
Review the past week's schedule regularly and adjust blocks that were consistently skipped or underestimated.
Questions
What is the most effective study technique according to research?
A review coordinated by psychologist John Dunlosky and published through the Association for Psychological Science rated practice testing (self-quizzing) and distributed practice (spacing study sessions over time) as the two techniques with the highest utility among ten commonly used methods.
Does highlighting or rereading notes actually help?
The same APS-coordinated review found highlighting, underlining, and rereading received low utility ratings, meaning they showed weaker evidence of improving retention compared with self-testing and spaced practice.
How does the Pomodoro Technique work?
According to a breakdown by Todoist, it involves working for 25 minutes on one task, taking a 5-minute break, and after four such sessions, taking a longer 15-to-30-minute break; the method was created by Francesco Cirillo in the late 1980s.
Is there solid proof that time management improves grades?
A study of 390 health-sciences students at the University of Sharjah found a strong statistical association between time-management scores and GPA, but the study authors themselves cautioned that the result likely reflects their specific, academically homogeneous sample rather than a universal rule.
How far in advance should students start studying for an exam instead of cramming?
The sources reviewed do not specify an exact number of days, but the Dunlosky-led review's high rating for distributed practice supports spreading review sessions across multiple days or weeks rather than concentrating them into one long session before a test.

Structured preparation, timed rehearsal, and a small set of anxiety-specific techniques — such as 4-7-8 breathing and reframing nerves as excitement — are the methods counseling centers and professional speaking organizations recommend for effective presentations. Fear of public speaking affects roughly a third of US adults, well below the often-cited 75% figure, according to a 2025 national survey.
In the 2024/2025 school year, Italian school principals earned on average about 100,000 PPS (purchasing power standard) while teachers earned around 35,000 PPS — a ratio of roughly 2.9 to 1, the widest principal-to-teacher pay gap among the 37 European education systems covered by the EU's Eurydice network. Italian outlets reporting the data on 18–19 October 2026 and the national principals' union say the gap stems less from high principal pay than from teacher salaries that have fallen behind inflation and other graduate professions.
Research on learning shows that how you take and review notes matters more than how much you write down. Studies point to three practices: use a structured layout that separates notes from cues, write by hand rather than type word-for-word, and review by testing yourself over spaced sessions instead of rereading.
An effective academic essay follows a clear path: a focused introduction with a thesis, body paragraphs that each develop one idea with evidence, and a conclusion that synthesizes the argument. University writing centers, including Purdue's OWL and UNC's Writing Center, outline specific techniques for building, organizing, and revising this structure.
