The most common mistake in topic review is re-reading your notes. Reading creates a feeling of recognition, not the ability to recall. Effective review is made of three things: closed-book recall, solving questions, and filling in the gaps.
Passive vs. Active Review
| Method | Type | Retention |
|---|---|---|
| Re-reading a note | Passive | Low — builds recognition only |
| Underlining / highlighting | Passive | Very low |
| Closed-book recall | Active | High |
| Solving questions | Active | High |
| Teaching it to someone else | Active | Very high |
The difference comes down to whether your brain is recognizing information or producing it. On the exam, you're asked to produce it.
A 3-Step Review Loop
- Closed-book recall (5 min). Look at the topic heading, close your notes, and write down everything you remember on a blank page — formulas, definitions, steps.
- Solve questions (15 min). Solve 10-15 questions on that topic. Mark the ones you got wrong.
- Fill the gaps (10 min). Go back to your source, but only read the parts you couldn't recall or got wrong.
That's 30 minutes total — shorter and more effective than re-reading the topic from the start.
When Should You Review?
If review isn't tied to a schedule, it doesn't happen at all. Use the spaced repetition logic with increasing intervals: 1 day, 3 days, 1 week, 1 month.
A practical approach: declare one day of the week (say, Saturday morning) a "review day." No new topics that day — just go through last week's material and whatever older topics are due for review.
What to Review First
Reviewing every topic with equal frequency wastes time. Prioritize in this order:
- Topics you got wrong on a practice test. This is where review pays off the most.
- Topics that show up frequently in the exam. Instead of perfecting a rarely-tested topic, solidify the ones that come up often.
- Topics you haven't touched in a while. A topic you finished two months ago is probably no longer fresh.
- Foundational topics that other topics build on. You can't do integrals without derivatives — review the foundation first.
Frequently Asked Questions
Spending roughly a third of your daily study time on review is a balanced ratio. That share should grow as the exam approaches — in the final month, review often becomes the bulk of your studying.
Whatever you write down during the closed-book recall step is already a note, and the most valuable kind. Re-copying notes from the source is usually a waste of time.
That means the topic needs relearning, not review. Study it from scratch and restart its review schedule from day one.
