Do I think the test is an accurate score of one's ability for Pharmacy School? No, I don't. I have little to no confidence that the PCAT tells AdComs anything more than "Can this kid take an exam under pressure?"
It wasn't easy for me, but it was mostly due to time management. I felt rushed through almost every section, especially RC & QA. During QA, I'd see math problems that were easy, but they were just entirely too long...so I'd make an educated guess and tag it for later so I can spend more time on shorter, faster problems.
In the end I thought was going to walk out with a terrible grade but to my surprise, my score was competitive.
It's a very odd test IMO. Not the hardest thing I've taken at all, just hard because you're pressed for time.
