<p>Can't seem to find a good conversion chart....</p>
<p>Does anyone know where I can find one? (Don't you dare say "The Internet") xD</p>
<p>Uh, so there’s no easy way to convert from 100-scale to 4.0, you need to just convert each grade individually and then average all that. An A is a 4.0, B is a 3.0, and so on, and a + adds 0.3 or 0.33 but a - subtracts the same amount.</p>
