If you read a proof of a theorem (e.g. a long and/or difficult one), and you fully understood every step perfectly while reading it, but cannot repeat it afterwards, would you say that your math ability has really improved much through reading it? Should you read proofs of theorems only if you know that you can repeat it afterwards, otherwise you are simply wasting your time and are better off doing exercises using the theorems? What are your opinions?
