Schweser Q Bank

Hi Guys How would you rate the Scheweser Q Bank? I have done quite a lot of questions from it. My average is about 78%. Can the level of questions compare to the real exam? I am taking the Schweser mock exam this weekend and plan to spend the last 2 weeks going through the 13 mock exams that I have. (including reviewing all the mocks). Please share your thoughts. Thank you. Janesha.
