How to Revise Effectively

  • Active recall: cover the notes, try to recall the key points, then check.
  • Spaced repetition: revise each chapter again after a day, then after a few days, then after a week or two.
  • Write, don't just read: writing key points and formulas out by hand helps them stick.
  • Teach someone: explaining an idea to a friend is a good test of whether you understand it.
