Process of Elimination/"Wrong Answer Tips" on SAT Subjects? (Math II & Chemistry)

<p>I am taking the SAT Bio, Math II and Chem tests on May 3rd. I was originally going to study equally for all 3, however, I found out after signing up that I need to get a 750 or over in Biology to get into a certain class at school. Since I already paid, I’m still going to take the other two, but I’m focusing all of my time on Biology (since I’m not doing too good). Are there any tips on “wrong” answers like on the regular SAT (eg. extremes)? If not, is there any stuff I should definitely review that will be on it? I’m in Honors Chemistry and Calculus this year, so I think I should be okay, but I’d like to do good.
Thank you!</p>
