I took the ATP written 3 times and it expired twice. Last time I took it was in August of this year and I didn't have any 135 questions on it. I took the 121 test. The other 2 times I think only a couple of 135 questions were asked but I can't really remember since it was in 2003 and 2006. When I took it in August, I only studied Part 121.
I also find it easier to understand the material instead of memorizing all of the questions. Just my two cents.
