Hi, I just took PCAT this morning and I used dr collins 2015. I think the type of math questions for collins are quite similar to PCAT. But I feel the real test problems looks more complicated (It may because English is not my first language and I am slow to understand those long questions). I also have time problem too!!! Some difficult in the middle and the last few questions are quite easy but I have already run out of time 🙁. Watch your time and few free to skip the hard problems in the middle.
