I just started working on the Acethedat. It has 3 full tests (you can take only once) and 2 full tests. So for PAT it is like having almost 5 tests. I am hoping it will give some practice.
My worry is ---- some people said science section has wrong (mistake) answers. (I havent checked).
I am having some doubts about top-front-end questions because some times I think they have wrong answers. Not sure. I am weak in top View. I could be wrong. For other things I can verify. Not For the Top-front-end view. So PAT in the acethedat may or may not have wrong answers.
Bottom line is At least for me acethedat will good practice. It is $50, not expensive.
