100Questions Exam Statistics

We usually advocate a passing mark of 70% to ensure a high level of confidence in the actual exam. This is especially so for the more difficult exams like PMP. Hence this gives you a good gauge of each exam's difficulty level.
Do note as well that the mean scores for the Free Exams generally trend higher, as there are many "repeat students" i.e. students that try several times until they obtain the perfect score - a testament to the saying "Practice Makes Perfect!"
