May I ask how you studied for the PCAT? I am assuming you used collins
I did start my work with Dr.collins, but the edition I used was 2014 version. Since the exam format changed, I needed a little extra information to fulfill the gap. For this purpose, I used Kaplan book purchased from amazon.

I repeated reading Dr.collins three times besides the math section.
I only skim through the Kaplan book.
Hope you find a better strats for reading section, but I can give you a little tip for science section.
After going through Dr.collins or any PCAT guides more than once, you'll notice there is a certain pattern in the question.
I compiled all the questions I got wrong in one notebook. This will allow you to be time efficient because you just have to read the topics you are lacking on and skip on the material you already know.
For a tip in math section, It is sometimes difficult to skip a question when you realized the answer is not in the listed choices. You spend 1~2 minutes already and hesitant to skip the question. SKIP IT and comeback later to find the error, but do not erase the notes on the marker board for that specific question.
Try to find other starts/advices people posted on forum and use whatever suits you the best.
GL with the exam!
