My composite practice exam is like 70-85... but my Biology was terrible. I took this at 3 am on 3 hrs of sleep (because why not? My kids were asleep so I had 4 hrs to spare...). I have not studied AT ALL and I've taken only one basic biology course... I have last years Dr Collins. I am registered for January. Does this say anything about how I may do? I took this as a base mark to see where I stand before studying. My courses end at the beginning of December and I plan on studying relentlessly for that month. My Bio was like horrific lol 20-30% I'm sure... What do you think? Can I study bio, chemistry and calculus and do decently on the PCAT?
