The way that the course and quizzes are structured allowed me to reinforce my knowledge and learn from my incorrect answers. In all honesty, I believe that the quizzes and practice exams were more challenging than the actual NASM exam. If you can achieve a 90% or more on the quizzes and practice exam, then you can be confident that you will be able to pass the NASM exam. You will also walk away with a good bit of practical knowledge!
