I took the PCAT today and I got a 98 after being in a similar position to you! I took 3 summer classes (physiology, calculus I, and speech) while working 2 jobs. Then I started my fall semester less than a week after my summer classes ended while still working 1 job. All in all I probably had 10 days of "real" studying time. You have more time than me, so you can use those extra days to get the 1 percentile higher than I did haha
I studied Dr. Collins exclusively. There were actually a handful of problems that were exactly the same as on the PCAT. Word-for-word the same question at least 5 times! I don't know how he does it! Although for bio I did have to think back to my pre-req microbio and gen. bio classes because he didn't go quite in-depth enough (for example, remember specific difference between gram+/gram- bacteria and some common infections/the bacteria that causes those infections. And brush up on the cell structures in some detail).
Also, when taking the exam there were some questions that at first I didn't think I had a hope of getting right. For example, there was a question about how an illegal drug causes a specific effect on the body (not sure how specific I'm allowed to be). I had NO idea. Never learned it. However, after examining the answer choices, there was only 1 answer that made sense at all (the wrong answers were about materials in the blood that didn't make sense, organs secreting substances are actually secreted by different organs, etc). This was true for bio, verbal, chem, and even at times quant. If you don't know the answer, always try not to let yourself panic and see if you can logically work it through with process of elimination. Works very well with verbal because some answers just don't make sense do to the structure of the sentence/analogy so you can immediately eliminate them.
The only thing I could have done differently to get a 99 was raise my reading score. I got a 95 or better in every section except reading where I got a 66. I didn't do practice tests for that due to my time constraints because I'm an avid reader already. But I wish I had practiced! I ran out of time because I was getting tired. Practice speed reading even if you don't think it's a rough area for you!
Good luck 🙂 Let me know if you want any other advice!
