The science section is stupid. They show you some graphs or tell you about the results of some experiment and then ask you a few questions about it.
The math and English (I think it's divided into reading and writing sections) parts will be more trouble. If one -or both- give you some trouble, just review them a bit. They're not going to throw you any curveballs on the math section, but you should know how to do a lot of different types of problems. For English, study where commas go or some s*** like that.
