Update. Took the Ace test and passed. I feel like Fitness Mentors play a good part in preparing me. I would recommend them. They were quite responsive (usually) when I had questions. I only wish there were more 150 question tests. I feel like it has been very helpful in preparing for the exam, which I will take in the next week or two. I guess then I could give a more accurate review as to how helpful it really was!!!
