<p>I feel that there’s no one area of bio that’s totally focused on. You should instead improve your weak points as much as possible. Taking AP bio usually increases your chances of a much higher score by a lot. Be committed, and look at prior practice tests. The tutor place I went to made a new test similar to the ones in Barron’s for us every week, so we took new practice tests every week. It was super helpful. Try to get a private tutor if you feel you’re lacking in any areas. Other than that, I hope you have a good memory because bio requires lots of memorization ^^ good luck~</p>
