May Biology SAT II Cramming

I have the Biology SAT 2 in less than a week. I am a freshman taking Honors Biology and I am also reading through the Barron’s book and taking notes on everything. I am only halfway through the book though. I only have a few days to left to make sure I know everything. Are there any sections that are overkill and are not necessary for the SAT? How do the Barron’s practice tests compare to the actually SAT? Biology is the only test I am taking so how much should I cram? Is an all nighter unnessesary or will it be worth it? Lastly, does anyone have any extra advice or tips?

The Plants chapter is overkill. Animal Physiology isn’t that important. Selection and Evolution is also overkill, it contains too much information. You can’t cram 2 days before the exam. The practice tests are accurate reflections, more or less, but the second test is easier. I got a 720 and a 770 on the practice tests, and a 730 on the real one.
