I tried the readysetpass exam simulator and found that they have scope for improvement.

Pros:
- Good coverage of the PMP material
- Questions ensure basic understanding of PMBOK
- Approach of gradually moving from baseline and specific knowledge area to to final exam

Cons:
- No mark for review option
- One needs to scroll down to get to next question and an annoying Timer keeps coming down causing distraction
- Many questions has capitalised keywords opposed to the claim
- Does not give post test summary/breakup of area-wise performance/score for baseline/final exam
- Answer explanation does not provide specific reference to source in PMBOK or other source material
- Encountered incomplete questions
- Most of the questions does not seem to be wordy enough
