You cannot possibly expect to score perfectly just after finishing your first read. There is an insane amont of material to go through so you tend to forget what you studied as you move on to next subject. Retention only comes when you put in more time and effort to revise the material and to practice the questions.
I agree reading the curriculum for the second time would really be a pain in ass, and that’s where these study guides come in handy. Their content is more exam-focused and I believe they do an efficient job in preparing you for the big day!
