I've just re-started preparing for PMP after a break of 5 month break. Today I did the Scope knowlegde area practice questions from Rita Fast Track and Edwell's end of chapter.

To my surprise I got 66.7% in Rita. In Edwell I got less than 40% correct. This is after I read the Pmbok chapter. I'm wondering how I should handle the knowledge gap. For example, Rita Fast track had over a 100 questions. If I look at each question, it will take me longer to study them and make notes than the time it took to do the 100 questions.
