<p>I've maintained a steady overall GPA of 3.54 my entire high school career. I'm currently finishing up my junior year. However, fourth quarter my grades drastically dropped from all A's and B's to three A's, three C's, and one D+. It was an unintentional drop, but nothing that I could prove to college admissions. I intend on returning to my A/B grades my entire senior year. How much will that one quarter affect my chances of getting into a good college?</p>
