Spaced repetition involves reviewing material at increasing intervals, starting with frequent reviews immediately after learning and gradually extending the time between reviews. This helps to reinforce memory and combat the forgetting curve. Active recall, on the other hand, involves actively retrieving information from memory rather than passively rereading notes or textbooks. This can be achieved through self-testing, flashcards, or teaching the material to someone else.
A sample schedule could involve reviewing new material daily for the first week, then weekly for the next month, and then monthly until the AP exam. Dedicate specific time slots to AP Biology each week, ensuring consistency. During each study session, focus on active recall techniques, such as answering practice questions or summarizing key concepts in your own words. Also, break down large topics into smaller, manageable chunks to avoid feeling overwhelmed. Remember to get adequate sleep and take breaks to prevent burnout and optimize learning.
