The trick is to switch from re-reading to retrieval. Chunk a chapter by subheadings, read a small section with full attention for 5–10 minutes, then close the book and write down everything you can recall in your own words plus one or two key formulas or diagrams. Turn each subheading into a specific question and answer it from memory, then reopen to check gaps and fix only what you missed. Build brief flashcards from those questions with tight prompts, and include drawings or worked steps where relevant to use dual coding. End the chapter with a two minute blank page brain dump and a 150 word summary from memory, then compare to the text and patch holes.
Use spaced recalls the same day, the next day, three days later, and a week later, each time answering your own questions or doing a short mixed quiz without notes. For quantitative subjects, follow each recall with two or three fresh problems that match the section objectives, and for concept heavy ones, explain the idea aloud as if teaching and generate one concrete example per concept. Time budget wise, plan roughly 2–3 minutes of focused reading per page plus 1–2 minutes of immediate recall and question writing, so a 20 page chapter is about 60–100 minutes on day one. Add two short spaced sessions of 15–25 minutes each in the following week, which is where most of the long term retention comes from. If a chapter is dense or you are missing more than a third of your recall during checks, slow the chunk size and use 25 minute blocks with 5 minute breaks, and interleave topics in later reviews to improve exam transfer.
