How does Carnegie Mellon calculate unweighted/weighted GPA?

<p>Every university seems to do it differently. Does it include freshman year? Does it include senior first semester? How many classes can be given the AP/honors bump?</p>

<p>I assume you’re talking about your high school GPA… It’s your high school that calculates it. College classes generally aren’t “weighted” in that way.</p>

<p>“At Carnegie Mellon we will use a students unweighted GPA for the admission process. If a school provides a weighted GPA we will re-calculate the GPA and place it on an unweighted scale. At Carnegie Mellon, we do not include freshman year when we calculate GPA, but we do take into account your grades in your senior year of high school.”
