Well I am a freshman in college this year and I plan on taking the PCAT next year so I am wondering when I should start studying for the PCATS? should I start now and review for like 2 hours each day until then?
If you're a freshman, that means you're about eight weeks into college.
Why don't you just focus on the classes you are taking now and worry about the PCAT later. You haven't covered really anything that is pertinent to the test and you may even change your mind once you get farther along in schooling.
The PCAT tests your acquired knowledge during your undergrad years. You're at undergrad weeks right now, just give it time.
