Just took the PCAT this afternoon too! IMO it seems about the same level as the practice tests Pearson offers.
I do want to say that reading seemed a lot harder on the real thing. I wasn't able to focus on the passages but still managed to do better compared to how I did on the practice tests, which is a miracle. I didn't even believe the score when I see the score report. My advice for the reading is to not overthink too much and just go with what you think (I was too tired to second guess myself like I did on the practice test). Passages are also not all science-based, some are social science/non-science.
Bio was harder than the practice tests, very specific stuff. Chem was okay, I struggled the most with Biochem stuff. The passages in these sections are not always needed to answer the questions, especially on Chem. I was able to cruise thru the whole Chem section without actually reading the whole passage, just glancing and pick out what's needed to answer the question.
Math seems very long to me. In the end I had to totally guessed on 4 questions without even reading them cuz I ran out of time. So I would stress timing on the Math section and practice a lot of quick math. Even though there is a calculator, quick math definitely helps as a non-scientific calculator isn't always super easy to use under a time crunch. Don't stress too much about calc. I haven't taken calculus since high school and had no trouble. Stuff that gave me trouble were arithmetic/algebra maths and some stats.
