Active recall works best when the question is small enough to answer without opening another tab. Turn a heading into one prompt, answer from memory, then check the source. The useful discomfort is the few seconds before you look; that pause tells you which ideas are available and which ones need another pass.
Keep the loop short
Five focused prompts today are more useful than fifty prompts you never return to. Save the misses and bring them back tomorrow. A small review queue is easier to trust, which makes it more likely that you will open it again.
Change the shape of practice
Mix definitions, comparisons, and “why” questions. A varied set teaches you to recognize the idea, not just its position on a page. After answering, add one sentence explaining the idea in your own words so a correct guess becomes a memory you can use.
Return on a schedule
Review new prompts later the same day, again tomorrow, and once more before the exam. The intervals do not need to be perfect; consistency matters more than a complicated formula. Your goal is a reliable conversation with the material, not a heroic cram session.
