What’s the best way to prep for the AP biology exam if my school has a bad teacher for it?

So I should start off by saying that I am looking to get into schools such as HYPS in 2 years and I’m sort of in a limbo between deciding to pursue the medical field or the law/politics field( I’m taking AP Government also) so it would probably be in my best interest if I can get a good enough test score on the AP biology exam if I do decide on pursuing a pre-med major. I probably am looking to get at the very least a 4 on the exam if I can, though I don’t really enjoy Biology at all nor am I really good at it. The main problem is my school (rural/town) does not have good AP teachers that prepare you enough for those exams and the AP Biology teacher doesn’t teach well in my (and most people’s) opinion, since no one in her class has ever made above a 3. Since the exam is 2 or so months away, I would want to prepare as much as possible before the exam which I’ve heard is one of the most difficult. I already bought the Princeton Review AP Bio prep book (don’t know if this is even the best prep book) but I would like to know if I can do anything else than just study from a prep book. Any suggestions for preparing for this exam would be appreciated, as this exam is really scaring me even though it’s a few months away…
