Study 5 times for an hour, not once for 5 hours

A marathon session the night before an exam is the worst possible use of five hours. Your brain doesn't store new information all at once — it stores it through repeated exposure spread over time, and this exact principle, known as spaced learning, can pull noticeably more retained knowledge out of the same number of hours. It's not some magic technique, just a matter of when you schedule those hours.

A typical scenario

Your anatomy exam is a week away and you have five hours of studying ahead of you. The classic scenario: Sunday evening, the night before the exam, you sit down and cram through the whole thing at once. By three in the morning you only vaguely remember the first chapter, the last one even worse, and during the exam your mind blanks exactly where you were most exhausted.

The alternative: you split those five hours across five days, one hour each, and schedule them into your calendar right on Monday. Every day you study a new chunk of material and start with a quick review of yesterday's. On the last day before the exam, you don't open anything new — you just run through everything once more. You walk into the exam having seen the material five times, not once.

How to do it

1. Break the material into logical blocks (chapters, topics, sections) and schedule them backward from the exam date — not according to “whenever I have time,” but a fixed date in your calendar.
2. Start each block with roughly 10 minutes reviewing the previous block before diving into new material. This short review is the core of the whole method — it's the “spaced repetition” that moves information from short-term into long-term memory.
3. Leave the last day before the exam entirely for review — don't open any new material. The goal of that day is to lock in what you know, not add more.
4. Write the blocks directly into your calendar as events, not as items on a to-do list. A task called “study anatomy” is easy to put off; a 5:00 p.m. Tuesday appointment isn't.
5. Build in a buffer — leave one day a week free to catch up on anything you missed. A plan with no room for slippage falls apart at the first illness or hard day.

The best tools

• The calendar you already use (Google Calendar, Outlook) — just add your study blocks as regular events with a reminder. No new app needed.
• Anki — a free spaced-repetition flashcard tool that calculates the optimal interval to show you material again on its own. Ideal for facts, definitions, and vocabulary.
• Quizlet — a simpler alternative to Anki with ready-made flashcard sets from other students and a test mode.
• Notion or a plain notebook — for tracking what you've reviewed and how it went; helps you spot which topics need more rounds.

What you get out of it

• Quality of retention: research on spaced learning repeatedly shows significantly better long-term retention compared to the same time crammed into one sitting — the difference is often noticeable even weeks later.
• Calm before the exam: instead of a late-night marathon and panic, the last day is just polishing material you've already mastered.
• Less burnout during the semester: an hour a day is manageable alongside everything else; five hours straight the night before a test isn't.
• A transferable habit: once you build this rhythm for one subject, it works just as well for languages, exams, and professional certifications outside of school.

Pro tip

Test yourself actively instead of passively rereading your notes — close the notebook and try to recall or explain the topic out loud, as if you were teaching it to someone else. Active recall combined with spacing it out over time is the combination that works best of all.
