I guess it depends on how you learn the best. I bought the “whole nine yards” package for my ACE personal trainer exam, but as it turned out, I only used the book (read it cover to cover) and wrote in my answers to the study guide, then made my own flash cards. I didn’t need all the extra stuff I paid for.
The prices for NASM must have gone up. 3 years ago, I think I paid about $800 for my materials, but I didn’t get the biggest package this time. One of my friends got an option that included just the book and a couple of practice tests. Then she used an app for her phone. Whenever she had down time, she answered the questions on the app. She passed with flying colors.
