Plenty of the answers are incorrect.
For example, which is not an input to the control scope process?
The correct answer was change requests, however it does appear in the answer list. Only verified deliverables and validated deliverables which are used interchangeably by the pmbok. And although "verified" is the technical term used in the pmbok (which the capm test is based on), it was chosen as the correct answer for this question, although incorrect.
Another question was "Which process within the time management area is used to monitor performance against the baseline..."
The answer is control schedule as it is the best answer in this case but it is not listed in the answer list. Instead, control scope (which is part of the Scope Management knowledge area) was supposedly the correct answer.
There are many questions that have 3 correct answers and one obviously incorrect answer within the answer choices, but the question is not "which is NOT" which it should be. I paid $20 for the full version of this app and its inaccurate and missing information namely the last two chapters of what is tested on for the capm exam. I would not recommend anyone purchase this app and I demand my money back for such a misleading service.
