What is the best way to review notes after class?

The most effective method is to review your notes within 24 hours while the material is still fresh, which dramatically improves retention. Start by filling in any gaps or unclear points you remember from class. Then use active recall techniques rather than just rereading: cover your notes and try to recite the key ideas from memory, or turn your notes into questions and answer them without looking. Spaced repetition is also critical. Briefly revisit the material after one day, then three days, then a week. Summarizing notes in your own words or teaching the concept to someone else forces deeper processing. Passive rereading feels productive but is one of the least effective strategies for long-term retention.
