Change how you study, and stay on top of your information. You won't be able to read everything, and read what it says in the schedule (the ones the teachers give you). I've found when they say they're doing something like respiratory, they only focus on certain topics, of course that's highly dependent on your teacher.
How are you taking your notes? Is it like how you did in your pre-reqs? When I was in nursing school
(I graduated last December), I had to overhaul my note taking and reading. I didn't highlight as much in my books, and what I really didn't understand, I went to my teachers. Have you looked at the rationales? Does it make sense when you read it?
For Pharm, I did charts and name associations. If it sounded like a pokemon, it's a psych drug (hey, it helped).
Oh, and another thing about taking notes -- don't just take notes for the sake of taking notes. Take notes in a way meaningful to you
. If that means writing in three different languages, so be it (...yes, I did that. There's only one other person in the world who can make sense of my notes).
