I used Fitness Mentors primarily for the test questions. I would take a chapter test and then study mostly for the test question subjects. Then I took 3 full exams and went back to review mostly for the answers I got wrong. Taking the tests over and over helped me retain the information needed for the actual exam which I passed easily the first time. Thanks so much for having the right questions on your exams. I would recommend Fitness Mentors to anyone.
