How often should a student review material when preparing for the exam?

Reviewing material regularly, spaced out over time, is a fundamental principle of effective learning known as spaced repetition. This approach leverages the spacing effect, which suggests that information is more easily retained when reviewed at increasing intervals rather than crammed in a short period. By revisiting the material consistently over time, a student can reinforce their understanding and memory, making the information more accessible during the exam.

When preparing for an exam, engaging with the material in a spaced manner aids long-term retention, reduces cognitive overload, and allows students to develop a deeper understanding of the subject, rather than just surface-level memorization. This method encourages better retention of knowledge and can lead to improved performance on the exam.
