So I am a 9th grade student in honors biology and I've signed up to take the SAT Subject Test in Biology (M for me) in June of this year. I know I am already behind so I've begun studying by taking practice tests from Princeton Review (found it online), the CollegeBoard, and a diagnostics test from Barron's. I've scored in the 660-690 range. What I've been doing is recording every single one of my mistakes and writing down in a notebook that I've dedicated for the sole purpose of study the concept that needed clarification or that I didn't know at all. I've also purchased the newest Barron's book and intend to study it cover to cover thoroughly. Is there anything else I can do that would boost my score to a 750+? Anything would help thanks!
