Jeffrey Grossman’s Secrets to Top College Grades

In 2019, professor Jeffrey Grossman at the Massachusetts Institute of Technology led a study that tracked the sleep patterns of college students and compared them to academic outcomes. Grossman’s team used wearable devices to monitor the sleep of 100 MIT undergraduates across an entire semester, capturing data on both sleep quantity and sleep regularity. They found that students who went to bed at consistent times and avoided very late nights—especially those who typically slept before 2 a.m.—achieved notably higher grades than classmates with irregular sleep schedules, even if total hours slept were similar. The mechanism behind this effect lies in the body’s circadian rhythms, which regulate alertness, memory consolidation, and focus. When students frequently disrupt these cycles by staying up late or varying bedtimes, their cognitive performance suffers during the day, reducing their learning efficiency and memory retention.

A 2020 study published in arXiv examined how underrepresented minority students in STEM disciplines often experience disparities in grades and attrition rates. The research highlighted that beyond individual study habits or intelligence, the broader academic environment plays a substantial role in academic outcomes. For instance, a lack of peer support, faculty mentorship, and inclusive classroom practices can contribute to higher dropout rates and lower grades among these groups. The mechanism here involves both psychological and structural factors—students who don’t feel a sense of belonging or access to resources are more likely to disengage from coursework, leading to reduced participation and weaker academic performance.

A study featured by bestcolleges.com analyzed the direct correlation between attendance, participation, and academic achievement. The research concluded that students who regularly attend classes and participate actively are more likely to earn top grades compared to their peers who skip classes or remain passive. The mechanism is twofold: attending class exposes students to material and explanations that may not appear in textbooks or lecture slides, and active participation—such as asking questions or joining discussions—reinforces understanding and aids long-term retention. Engagement with instructors can also clarify confusion early, preventing minor misunderstandings from snowballing into larger academic difficulties.

In 2024, research published in arXiv explored the motivational effects of receiving numerical scores versus letter grades. The analysis determined that, under certain conditions, numerical scoring systems (such as percentages) can foster better student motivation than traditional letter grades. The cause is that numerical scores offer finer-grained feedback, making it easier for students to track incremental progress and set concrete goals for improvement. When students can see a precise score, rather than a general letter, they’re more likely to recognize areas for growth and stay engaged with the material.

The University of Cincinnati has emphasized the importance of active learning strategies in improving student grades. Their guidance, featured in a 2025 article, recommends techniques such as self-quizzing and teaching concepts to others. The effectiveness of these strategies comes from their demand for retrieval practice—when students actively recall information rather than just reviewing notes, they strengthen neural connections and deepen understanding. Teaching a concept to someone else requires organizing thoughts and filling knowledge gaps, which makes the learning more durable and less susceptible to forgetting.

A 2021 study found that accuracy in student self-reporting strongly correlates with higher academic success. Students who are able to honestly and accurately assess their own study habits, understanding, and performance tend to earn better grades. The underlying cause is that self-aware learners can more effectively identify strengths and weaknesses, allowing them to adjust their strategies and seek help where needed. Inaccurate self-assessment, by contrast, leads students to overestimate their preparedness or misunderstand what’s required, resulting in lower performance.

Mixed enrollment patterns, where students alternate between full-time and part-time study, have been shown to yield academic outcomes closer to those of full-time students. Research published in arXiv revealed that these students significantly outperform those who enroll part-time consistently. The mechanism is tied to both academic momentum and social integration: mixed-enrollment students maintain stronger connections with their peers and campus resources than part-time students, and they’re better able to manage workload fluctuations while preserving continuity in their learning.

Casey LaMarca, Associate Creative Director and Instructor at Southern New Hampshire University, described the transformative impact of academic achievement on students’ confidence. She observed that seeing tangible progress, such as earning an A on an assignment, can change a student’s perception of what they’re capable of accomplishing. The effect occurs because recognition of success provides external validation, which boosts self-efficacy and encourages further engagement and effort.

Heidi Lupo, Senior Director of Undergraduate and Graduate Operations at Bellevue University, has stressed that academic success is driven more by discipline and planning than by innate intelligence. Her assessment points out that “intelligence alone doesn’t guarantee results,” and that students who intentionally structure their study schedules, set goals, and follow through with preparation generally outperform those relying on natural ability. The underlying cause is that planned, consistent effort enables students to overcome knowledge gaps and stay on top of assignments, while even highly intelligent students can fall behind when lacking organization.

Sleep is not only about duration but about regularity. Jeffrey Grossman’s MIT research found that students who maintained a sleep schedule—going to bed and waking at similar times each day—performed better academically, even if their nightly sleep averaged the same as less regular peers. The body’s circadian system needs stability to regulate hormones like melatonin, which directly influence concentration, mood, and cognitive accuracy. When students disrupt their rhythms with varying sleep times, even the same total hours can yield less restorative rest and weaker mental performance.

The University of Cincinnati’s recommendations include self-quizzing as a method superior to passive reading or highlighting. When students quiz themselves, they mimic the retrieval process used in exams, which strengthens the neural pathways associated with recall. This mechanism, known as active recall, reinforces memory and makes information more readily accessible during high-pressure testing environments.

Teaching others, another active learning strategy highlighted by the University of Cincinnati, forces students to reorganize information, fill in gaps, and articulate concepts in their own words. This process shifts passive familiarity with material into deeper mastery, a phenomenon termed the “protégé effect.” The mechanism ensures that gaps in knowledge are exposed during teaching attempts, prompting further study and clarification.

In 2021, a research team found that students who are honest and precise in self-reporting—such as accurately logging study hours or truthfully assessing understanding—tend to perform better academically. This relationship exists because self-awareness allows students to identify weaknesses and target their efforts more effectively. Overestimating one’s skills can reduce the motivation to review or seek guidance, leading to poorer grades, while accurate self-reflection supports continuous growth.

A study of enrollment patterns published in arXiv found that students who alternate between full-time and part-time enrollment perform nearly as well as those who remain full-time, and substantially better than students always enrolled part-time. The mechanism behind this pattern involves both workload management and social engagement: mixed-enrollment students can balance academic commitments with other responsibilities without fully disconnecting from institutional support and peer networks.

Research reviewed by bestcolleges.com found that students who missed class or were disengaged during lectures underperformed even when controlling for intelligence or previous grades. The cause is that in-person attendance exposes students to not only course content but also to spontaneous questions from peers, instructor insights, and nuanced explanations not found in textbooks. Participation further enables real-time feedback and clarification of misunderstandings.

The 2024 arXiv study on grading motivation suggested that numerical feedback—such as receiving a score of 87 out of 100 rather than a “B+”—encourages students to focus on specific areas for improvement. The psychological mechanism is that percentages or point totals provide actionable benchmarks, whereas letter grades obscure detail and may not motivate incremental improvement.

Heidi Lupo of Bellevue University has emphasized the importance of planning and discipline. She argues that students who develop and stick to structured study routines, set concrete goals, and regularly monitor progress consistently outperform those who simply rely on intelligence or last-minute preparation. The mechanism here is that planned, spaced effort enables better long-term retention and reduces the stress and inefficiency of cramming.

Casey LaMarca at Southern New Hampshire University has observed that the experience of academic success, like earning a high grade, can fundamentally change a student’s outlook on their own abilities. This is due to the psychological effect known as self-efficacy: when students see concrete evidence of their competence, they gain confidence and are more likely to tackle challenging material in the future.

MIT’s 2019 sleep study, led by Jeffrey Grossman, used actigraphy watches to objectively track students’ sleep and found that not just sleep deprivation, but irregular sleep patterns—especially inconsistent bedtimes—were robustly associated with lower GPAs. The biological mechanism underlying this effect is the destabilization of the circadian rhythm, which impairs memory consolidation and learning during key sleep phases.

Research from arXiv in 2020 revealed that disparities in STEM achievement aren’t solely a matter of individual effort but are tied to broader institutional factors. Students from underrepresented groups face structural barriers, such as limited access to mentorship or inclusive study environments, that can hinder academic progress. The mechanism involves both reduced support and increased psychological stress, both of which negatively impact learning and persistence.

The University of Cincinnati’s recommendations for active learning also include elaboration—explaining ideas in one’s own words and making connections across topics. This cognitive process helps integrate new information into existing mental frameworks, promoting deeper understanding and better recall.

Bestcolleges.com reports a direct, positive correlation between consistent attendance and higher grades, regardless of subject or major. The mechanism is that each session missed not only means lost exposure to material but also compounds learning gaps over time, which makes catching up increasingly difficult.

A 2021 study published in arXiv found that students with high accuracy in self-reporting were more likely to use evidence-based study strategies, such as active recall and spaced retrieval. The underlying cause is that honest, reflective learners are more receptive to feedback and adaptive to new methods that increase retention.

In the field of medicine, professional programs frequently emphasize the importance of attendance, participation, and active engagement due to the volume and complexity of material. Students in medical courses who miss lectures or fail to participate often struggle to keep pace, as much of the learning involves case discussions, hands-on demonstrations, and clinical reasoning exercises not captured in textbooks.

The University of Cincinnati article from 2025 states that teaching concepts to others is especially effective in technical or detail-oriented fields, such as medicine, where mastery requires both factual recall and conceptual understanding. Acting as a tutor or study group leader forces students to clarify their understanding and anticipate questions, which strengthens both memory and analytical skills.

The 2024 study on grading motivation found that numerical scoring was particularly effective for students in challenging majors, where progress can be incremental and letter grades may not reflect nuanced improvement. In medicine, for example, a shift from 75% to 82% on an exam can indicate mastery of complex material that a “B” grade would not reveal.

The University of Cincinnati’s active learning recommendations are supported by cognitive psychology research, which has shown that repeated retrieval and elaboration facilitate long-term memory storage in the neocortex, making information more durable and less likely to be forgotten under academic stress.

A review by bestcolleges.com found that students who combined regular attendance with active participation—such as contributing to discussions, answering questions, and engaging with instructors—outperformed classmates across all grade point averages and majors. The mechanism is that active engagement produces a feedback loop: verbalizing concepts reveals weak areas, and instructor feedback enables real-time correction.

A 2021 arXiv study also found that students with accurate self-reporting were more likely to seek out and effectively use academic resources, such as campus writing centers and library services. The mechanism is that self-aware students can identify when they lack understanding and proactively pursue help, which directly improves their grades.

The same research noted that students who accessed library resources—such as scholarly databases, research guides, or medical journals—scored higher on written assignments and research projects. In medicine, the ability to navigate resources like PubMed, clinical guides, and reference texts is directly linked to both classroom grades and performance on licensing exams.

The University of Cincinnati urges students to join or form study groups, especially in demanding majors like medicine, where collaborative learning enables members to pool knowledge and clarify complex concepts. The mechanism is that group explanation and questioning expose misunderstandings that can be corrected before exams.

A study on enrollment patterns published in arXiv observed that students who alternated between full- and part-time status maintained higher GPAs than those enrolled only part-time, likely because mixed-enrollment enables better balancing of academic and life demands without losing academic momentum or campus connections.

Casey LaMarca notes that academic success can spark a student’s belief in their ability to achieve even more. In medicine, where exams and practicals are especially challenging, each academic victory can sustain motivation through rigorous professional training.

Research reviewed by bestcolleges.com also found that students who participate in class discussions report greater satisfaction with their learning experience, which translates into stronger commitment and persistence in their studies. The mechanism is that active involvement increases a sense of ownership and accountability for learning outcomes.

Heidi Lupo’s insights at Bellevue University underscore that planning and discipline are critical in medicine, where the sheer quantity of required knowledge makes passive studying or last-minute cramming ineffective. Structured routines and consistent review of material over time are necessary to master dense, cumulative subjects.

MIT’s sleep research team, led by Jeffrey Grossman, determined that sleep consistency is particularly important for students facing high cognitive loads, such as those in medical programs. The mechanism is that memory consolidation, which primarily occurs during certain sleep cycles, is most effective when sleep is regular; erratic schedules disrupt the sequence of these cycles and impair the transfer of information from short-term to long-term memory.

The University of Cincinnati’s self-quizzing recommendations are supported by evidence that active recall is more effective than repeated reading for long-term retention. In medicine, self-quizzing with practice questions or clinical scenarios is a primary method for preparing for board exams, as it mirrors the retrieval demands of high-stakes testing.

A 2021 study found that accurate self-reporters were also more likely to break complex assignments into smaller, manageable tasks, a strategy associated with higher performance across challenging curricula, such as medical education. The mechanism is that this approach reduces procrastination, eases stress, and ensures steady progress through dense material.

Research from arXiv in 2020 demonstrated that institutional factors, such as access to mentorship and an inclusive climate, can significantly affect grade outcomes and persistence for underrepresented students in medicine. Schools that foster support networks see higher retention rates and better academic performance among minority students.

Bestcolleges.com’s analysis found that students who reviewed material soon after class—rather than waiting until right before exams—retained information better and earned higher grades. The mechanism is that immediate review leverages the recency effect and strengthens initial memory traces before forgetting occurs.

A 2021 arXiv study observed that students who accurately self-report were more likely to seek feedback on assignments and incorporate suggestions into future work. This feedback loop is critical in medicine, where continuous improvement is essential for mastering complex, evolving content.

In the 2024 arXiv study, numerical scores were found to be particularly motivating for students in technical majors when paired with detailed feedback. In medicine, seeing a specific percentage and understanding which questions were missed allows students to target review and focus on high-yield topics, directly improving subsequent scores.

The University of Cincinnati recommends that medical students use active recall with clinical cases and flashcards, as these methods promote retrieval of both facts and reasoning processes needed for diagnostic skills. The mechanism is that regular practice with real-life scenarios strengthens problem-solving ability and prepares students for clinical rotations.

This technique, especially when applied using flashcards or clinical questions, is proven to improve long-term retention in high-volume fields like medicine.

A 2021 arXiv study found that students who honestly tracked their study time were more likely to adjust their strategies mid-semester, such as increasing hours before challenging exams or seeking support for difficult topics. The mechanism is that real-time tracking enables responsive adaptation, leading to better grades and reduced risk of falling behind.

Research into enrollment patterns, as reported in arXiv, showed that students who maintained at least some full-time enrollment—rather than shifting entirely part-time—benefited from greater access to campus resources, including libraries, academic advisors, and peer study groups. This access is strongly correlated with academic persistence and higher grades, particularly in intensive majors like medicine.

Bestcolleges.com’s review concluded that students who engaged in regular self-assessment, such as reflecting on what they did or did not understand after each class, were more likely to identify knowledge gaps early and seek clarification. The mechanism is that early detection of misunderstandings prevents accumulation of errors and last-minute panic before exams.
