Preparing for exams at medical school is a challenge that requires not only diligence, but also the right strategy. The neurobiology of learning shows that many popular methods (rereading, highlighting) are ineffective, whereas evidence-based techniques (spaced repetition, active recall, interleaving) yield 20–60% better results. This article covers 7 evidence-backed methods.
1. Active Recall
Core concept: instead of rereading your notes, close your textbook and try to recall the information on your own (tests, flashcards, questions). Every retrieval attempt strengthens neural pathways.
- Effectiveness proven by a meta-analysis by Dunlosky et al. (2013) — rated as "high utility"
- Testing improves retention by 50% compared to rereading (Roediger & Karpicke, 2006)
- How to apply: after reading a topic, close your notes and write down everything you remember. Then check and fill in the gaps. Use platform tests
2. Spaced Repetition
Core concept: review material at increasing intervals (1 day → 3 days → 7 days → 14 days → 30 days). Ebbinghaus's forgetting curve shows that without review, up to 70% of information is lost within 24 hours.
- Algorithms: SM-2 (SuperMemo), FSRS (Anki)
- How to apply: create flashcards (Anki) for each topic immediately after the lecture. Review them daily for 20–30 minutes. Over the semester, accumulated reviews will build solid knowledge for your exams
- Particularly effective for factual data: drugs, classifications, anatomical structures
3. Interleaving
Core concept: instead of blocked studying (4 hours of anatomy, 4 hours of physiology), mix up topics within a single study session (cardiac anatomy → cardiac physiology → cardiovascular pharmacology → 30 min of anatomy of another organ).
- Studies show a 20–40% improvement with interleaving vs. blocking (Rohrer, 2012)
- Interleaving forces the brain to choose the correct strategy → better differentiation of similar concepts
- It initially feels harder — this is a "desirable difficulty" that ensures better long-term retention
4. Feynman Technique
Core concept: explain a topic as if you were teaching it to a child. If you cannot explain it simply, you do not understand it well enough.
- Choose a topic (e.g., "cardiac cycle")
- Explain it in simple language on paper, without a textbook
- Identify gaps (places where you got stuck or used jargon)
- Return to the source material and fill in the gaps
- Simplify your explanation once again
Especially useful for complex topics: biochemical pathways, mechanisms of drug action, disease pathogenesis.
5. Pomodoro Technique (Time Management)
- 25 minutes of focused work → 5-minute break
- After 4 cycles — a long break (15–30 minutes)
- During the break: stand up, walk around, drink water. No phone!
- Helps combat procrastination: "25 minutes isn't that scary"
6. Sleep and Physical Activity
Sleep is not a luxury, but a part of learning:
- During NREM sleep (slow-wave), the hippocampus "replays" daytime experiences → memory consolidation
- Sleep deprivation reduces cognitive function by 25–40% (equivalent to a blood alcohol concentration of 0.5–1 ‰)
- 7–8 hours is the minimum for a medical student
- Studying right before bed (without screens!) → best consolidation
Physical activity:
- 30 minutes of aerobic exercise → ↑ BDNF → enhanced neurogenesis in the hippocampus
- Even a 10-minute walk between study sessions improves concentration
7. What DOES NOT Work (or Works Poorly)
| Method | Efficacy | Why |
|---|---|---|
| Rereading notes | Low | Creates a "fluency illusion" without actual retention |
| Highlighting/underlining | Low | Passive processing, requires no cognitive effort |
| Cramming the night before | Low long-term retention | Works for tomorrow's exam, forgotten in a week |
| Making pretty notes | Mean | Often turns into copying (a passive process) |
Frequently asked questions
How many hours a day should you study?
Studies show that productive concentration is limited to 4–6 hours a day (excluding lectures). Quality matters more than quantity: 4 hours of spaced active recall is more effective than 10 hours of passive rereading. Distribute your workload: mornings for complex subjects (biochemistry, anatomy), evenings for flashcard review.
How many days before the exam should you start preparing?
Ideally, study throughout the semester (spaced repetition). But if you are starting "from scratch": for a voluminous exam (anatomy, pharmacology) — at least 2–3 weeks. First week — review all topics with active recall. Second week — interleaving + practice tests. Third week — tests and filling gaps only. Last day — light review, early sleep.
Start your preparation with the subject catalog on the platform. Try gia tests for self-assessment. Related articles: anatomy tests, Krebs cycle, ECG.
