Practice practice practice (I made flashcards for EVERYTHING, didn't buy any books, I'm broke lol). Ochem is a lot memorization, like memorizing mechanisms, reagents, and nomenclature. You'll begin to see trends as you practice mechanisms and things like that too which helps a lot for exams when the professor gives you a crazy synthesis problem or something. Also make sure you know the big ideas, like why is product X more favorable than product Y, what causes event X to happen instead of Y, stuff like that.
Bottom line, if you just put in the time to study each day, I think you'll do exceptional. I think I spent more time on Ochem I and II than all my other classes combined that year... It was a lot of work but when the exams rolled around I was prepared, confident, and killed the exams.
Good luck OP! I tutor Ochem too, feel free to PM me if you want to chat more about study tactics or whatever.
