Hey, so I am taking 3 AP's this year Lang. and Comp., Psych, and APUSH. I have a few prep books for each subject. I just want to know how to use those books as efficiently as possible. I am prominently concerned about Lang because my teacher will write me a superb recommendation if I get a 4 or 5. If you have scored a 5 on any of these tests please feel free to share tips, strategies, or study plans. Thanks!!!
