I decided to do ACSM’s self study because it was affordable and I liked the video lectures. The lectures are available to you for up to 6 months while you study and prepare for the exam. I found it helpful to listen to each lecture once then go back and listen to them again but taking notes the second time. I studied from the book and the lecture notes before taking the exam. I passed the first time with a very good grade. Everyone learns differently. But if pricing is an issue for you, check out other options. ACE, AFAA, ACSM are all good options and much more affordable.
