Hey PrePharmVet,
For the quantitative section, I highly recommend doing an initial sweep through the questions and only answering the easy questions that you can complete quickly. Then, after you finish all of the quick and easy ones, go through and work on the harder questions that you know how do to. After these are complete, try working on the hardest ones that you might not know how to do. This way, even if you run out of time trying to figure out the hard ones, you still have all of the points for the easier questions. This alone will put you ahead of the other test-takers who try to chug through each question in sequence. Math was my worst section, and even after running through and doing all of the easy questions first I only got a 72 on this section, but that score is a lot better than what it would have been had I tried to do each question in order.
Have you tried using the Pearson practice tests? These helped me a lot when practicing for my PCAT. The questions they ask are very similar to the actual PCAT, and they have timers for each section that help you get a feel for how quickly the actual test progresses. I think the timer is quite useful for the reading and math sections. I've also heard that using MCAT prep books for the reading section is good practice for the PCAT, but I don't have any personal experience with this resource. I hope this helps!
