Hi Tyler,
Our rule of thumb is: If you consistently answer 70% of questions that you have never seen before correctly, you can consider yourself to be ready. This 70% rule is, of course, only a generalization. Everyone is different and there is no guarantee that a score of >70% will ensure that you pass the actual Project Management Professional (PMP)®
