<p>Hey, I'm going to be taking the SAT Bio test in June and I've started preparing with Barron's and PR. I am almost done with Barron's, so PR will just be a basic review to refresh all the topics. I was wondering what topics would be mostly focused on in the tests, especially for the topics I am more confused on (like plants and human physiology). Also what kinds of questions do they really like to focus on. I'm taking the M test if that helps. Also feel free to tell me how you studied. I'm aiming for an 800 and I really help I am preparing enough for it!</p>
