PCAT study guide from pearson doesn't help bro. It's an old test. think about it. they don't use it as a practice test but only so u feel test out hence only $25 as oppose to higher fee for prac test 234. Trust me i used it and it didn't help. had 65 then 38 on chem using only pearson prac test and study guide. pearson sucks cause it doesn't have enough prac questions ull face on real test day. but that doesn't mean u shouldn't do your best learning as much you can. u should do collins and then see if pearson prac test 234 can be tackled. i used pearon then collins. if i did collins, first i wouldn't have to waste time studying and retaking this stuff 4 times.
use collins friend.
i made mistake spending 3wks on collins study guide memorizing learning everything. found out i retained 80%-75% when I did his prac test and needed revisit study guide re-learn some stuff. best way learn is do your best on reviewing study guide but don't be perfect at it and then do prac quest from collin. you'' realize making mistakes is best way to learn. hey, prolly you should even do question first to get a feel, mix and math and experiment dont be scared 🙂 trust yr intuition as it is shaped as you progress thru material.
