SAT II Biology Molecular Tips?

Hey everyone I’m taking the SAT II Molecular Biology exam and I just purchased the Barrons E/M Bio 5th edition book. I was wondering if anyone had any study tips or tricks to use on the exam to get a good score? I’m trying to get a 800! I’m taking the subject test in June 2017 right after I take my AP Biology exam. I just finished my freshman year in Biology Honors and my grade was an A. I’ll be going to AP Biology in the 11th grade and currently I’m about to go to my sophomore year. I’ll also be purchasing an AP book to study next year,
