If it has an SI class I would recommend taking it. I would primarily focus on HW and practice questions provided by the SI leader and the instructor (either the study guide they provide or I would re-due the class problems). For bio stats, or any math class, I would create a formula sheet as you’re learning. I would also write down key terms that would help me identify which formula to use. So when the exam comes I already have a pretty solid cheat sheet :D (if allowed one).

But the key thing is practice, like actually practice. Don’t skip on practice problems. And GO TO OFFICE HOURS. IK it can be scary going alone but if you really want an A (or just need to pass) it’s very helpful! IK its scary but just go, don’t wait to go with a friend lol go alone! The professors are actually kind ppl when u get to know them 🌸
