i'm a certified operator for music and post
the post test was a lot harder than the music. maybe that's just ebcause my focus with pro tools was music, and not post. Honestly, if you study the book, and know it inside and out, you should be good. you get 3 chances to pass the test. and each time you dont pass, they tell you the sections of the book to study, which really helps you out, because it will tell you a particular section. once you go read that section, in most cases you remember what question it was you got wrong, and then you know it for the next time.
