<p>Okay, so I didn't get a very good grade in the first semester of my AP Calculus AB class. I bought a Princeton Review book and have started studying. So I think I will get a good grade the second semester and do well on the AP exam. However, I'm thinking about just retaking the first semester of AP Calculus AB during the fall semester of next year. If I do this, will the grade I get next fall replace the grade I got last semester???</p>
<p>that depends on your school... - talk to your counselor</p>
