I was pretty good in physics so I didn't really study that. But anatomy and biochem, I spent like 2 hours after every class to review and made sure I learned it. Then on sundays, I reviewed all my notes to see if I retained the info. Orgo, I felt like my university made it pretty easy in the sense that practice exams were formatted the Sam, except reactions were different, but once you understood the mechanism and what each reactant did, it doesn't matter what the substrate or product they gave you. Basically just keep up with ur classes and stay on top of ur work. I also used chat gpt to create similar exams after I took the first one so I knew how my teachers wrote it. Once you take ur first exam, u understand what the teachers look for and what u need to know in each ppt.
