<p>Weighted = Both regular and honors/AP classes count in your GPA, but honors/AP classes are worth more points. This is done for class rank purposes within individual high schools so that kids who got straight As in regular classes won’t automatically be ranked higher than kids who got slightly lower grades in more challenging classes. Usually this is on a scale higher than 4.0. </p>
<p>Unweighted = Both regular and honors/AP classes count the same in your GPA. The weight a course is given depends only on the number of credits it was worth. The simplest/most common unweighted scale says A = 4, B = 3, etc. but there can be more complicated ones with plus/minus grades. They don’t have to be on a 4.0 scale either (your school appears to use a 4.3 scale), but you shouldn’t compare two GPAs that are on different scales.</p>
