<p>So I’m taking summer school for the first time this year and I was wondering what is the highest grade you can possibly get so that I can strive for it because I know I messed up during the school year and want to make amends for it. </p>
<p>I’m not sure where you’re from, but here in Chicago they’re implemented a new system where you get to replace the grade of the class you failed with the grade you got in the summer school class(aka replace an F with an A). So check with your GC and see if your school system follows the same system.</p>
<p>TL:DR The highest grade you can get is an A.</p>
