My personal course was through ACE and you can find a lot of great stuff out just by going to their website www.acefitness.org/ or calling them direct Phone: (858) 279-8227 . It took me about 3 months to study up and take the test but I had previous experience so it was easier for me. A friend of mine took alittle more than 6 months to take the test. All it required for me was purchasing the book and the practice test. I definitely suggest getting the practice test, it helps you get a feel for the style of test before you take it. Again though, my same friend took three chapter review courses for it but the cool part was the went towards his cec’s for his recert once he passed. Hope our story helps.
