Skim the chapter first to collect the headings and bold terms and then write three questions you must answer. Read one subsection with a pencil, then close the book and blurt the key ideas and definitions on paper from memory. Check the text for gaps and fix your notes in a different color so you can see what was recall versus copy. Do this stop and blurt loop for the whole chapter in small chunks.
End each session by making a one page summary from memory, no peeking, then verify and trim. Next day, redo the summary in five minutes and add only what you truly forgot. Two days later, test with a blank sheet and answer your three questions again. If accuracy is under eighty percent, reread only the missed parts and retest. Use the same process on practice problems or end of chapter questions and write out answers cold. This is simple active recall plus spaced repetition, and it works.
