how do you go about recording errors ? do you solve a complete set and then check and log the answers or do you check the answer and record errors after every problem ?
I'd do a set of at least 37 questions, writing down the answers on paper, and marking the questions I'd like to review later either the answer or the method to solve the problem. When finished, check the answers, and write in the
error log all the wrong answers plus the ones I had doubts when solving (even if I got the correct answer). Then, I'll review how to solve all of them in the guide, and when finishing the guide would redo all those problems, and see how I perform. Most likely I still won't get all of them right, so I review the most difficult problems for me again at the end of the preparation.
