I have read from Rita's book where she has mentioned the Number of times a particular type of question has appeared on the actual exam. This information guides one on the level of focus to assign such a topic.

(i) How does Rita know that a particular type of question has appeared only 3 times, 2 times, or never on the actual exam?

(ii) Does PMI have any repository of past questions just as ACCA, CFA do?
