it said "“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.”
I know CMU only looks at Sophomore and Junior year grades, but does CMU differentiate between the +s and -s. Is an A- and A both 4.0 or is there a difference?
