<p>Okay, I'm trying to figure something else out. I figured out once I turn something in my homework grade will raise from 115.8 to 121.5, however when I add the three "categories" together, and divide by the total (300) I always get 91, BUT it should be 87%, which is currently my overall grade. </p>

<p>To get overall don't you just add up the percents and divide by the total? I keep doing this, but I don't get 87%, and I know that my teacher doesn't make certain categories worth more. So, like homework isn't 70% and tests aren't 30%, this teacher doesn't have it.</p>

<p>Can someone help me to identify what I'm doing wrong?</p>

<p>68.0
115.8
92.1</p>

<p>Maybe they're weighted differently?</p>

<p>It's possible that maybe they are weighted differently and you don't know it?</p>

<p>Maybe they're based on points rather than percentage. Then they'd be weighted differently.</p>
