I highly recommend purchasing the prinston review and crash course book. I’m completely mind blow that I actually got a 5 on this test. I read the book in class (sometimes) but we skipped over so many chapters. I was completely unprepared for the test because the teacher sucked and I was essentially teaching myself the class. Also look up YouTube videos there are many videos that are long and I would recommend watching all of them in a series. I used joczProductions if any of you are curious. If you have any other questions let me know. I also got a 5 on psych, 4 on enviro and a 3 on bio and world, so if you have any questions about that you can comment.
