I have been an AFAA personal trainer for three years. I was familiar with the gym and specific exercises to work particular muscle groups. However, the weekend workshop is just an overview of everything that will likely be on the test. Some people go to the workshop thinking that they will learn the material at that time. However, it is used for review. I studied really hard for at least three months before the test since my sister is also certified by AFAA. When she told me what the practical (applied) test involved, I realized that the written test is one thing (the multiple choice answers are on the page). However, the practical was much more difficult since you don't know what questions will be asked, you have to "work" with a "client" (another student) and answer a bunch of other questions verbally. I don't think AFAA gets the attention it deserves as far as credibility is concerned. When working with clients, book-smarts is one thing. However, knowing how to communicate the information puts things on a whole other level. I hope this helps!
