<p>To add even more light to the 4.0 scale...here's how our school does it: </p>
<p>A+'s are given special bonuses so its actually a 4.3 scale, Honors and AP classes are all 1 point higher on a 5.3 scale. It works out like this...</p>
<p>4.3 = A+
4.0 = A
3.7 = A-
3.3 = B+
3.0 = B
2.7 = B-
2.3 = C+</p>
<p>etc...</p>
<p>So if it is an honors class you add a point to that class. then you just add up all your class GPA values and divide by the number of classes to get overall GPA. that way there's no ties ever like someone noted earlier. Yeah, I know it's really weird. You NEVER hear of schools doing a 4.3 for A+s but we're really dumb. Oh well, I got valedictorian out of it so it was ok with me! No I'm just kidding, but seriously that's just how it works for us, if anyone cares...</p>
