I just bought the Gleim ATP written book and I wanted it just because I could reference it and whatnot. But my questions is: Since i'm currently attending ATP, should I take the test with them since they will give me a discounted price of $200 to take the test, or just study the Gleims and pay like $90 at some other place? Most of the people i've heard of and seen take the ATP written at ATP have all passed and did the prep software for like 8 hours and then take the test all in one day.
