<p>You need to find out about your high school’s policy on academic honesty, and contact your counselor just in case. I assume your teacher would do whatever he or she wants but if you did not cheat then you really need to prove that you did not. Because At this point of your high school career, academic honesty is very serious (compared to, for instance, cheating in 9th grade). </p>
<p>I’m not sure how any college would review academic dishonesty, but I think this can screw up your chances. I don’t think you want to tell any college about it yet. Just focus on vindicating yourself.</p>
