<p>Is it calculated per-semester, or per-class? For example:</p>
<p>Per-semester:
Grade 9: 3.8; 4.0
Grade 10: 4.4; 4.2
Grade 11: 4.8; 4.8
Grade 12: 5.0; 4.8</p>
<p>You would add them up and divide by eight (for the eight semesters).</p>
<p>OR</p>
<p>Per-class:
Grade 9: 4, 4, 4, 4, 3; 4, 4, 4, 4, 4
Grade 10: 5, 5, 4, 4, 4; 5, 4, 4, 4, 4
Grade 11: 5, 5, 5, 5, 4; 5, 4, 4, 4, 4
Grade 12: 5, 5, 5, 5, 5; 5, 5, 5, 5, 4</p>
<p>You would add them up and divide by forty (the number of classes taken)</p>
<p>It may not seem like this matters, but it does. For example, I could take only three classes junior year (with cc classes to substitue) and have them all APs with a 5.0 GPA. But I would have the same GPA if I was to take six or seven APs (and get all As).</p>
