Different schools calculate GPA differently. In the case of the OP’s D, the school calculated the scholarship according to its policies.
My S was just under the GPA requirement for the next-bigger scholarship amount at his top choice school. His acceptance included a scholarship amount. After his first semester senior year grades came in, his GPA actually met the criteria for the larger scholarship. He contacted the school, and they gave him the larger amount. Even then (class of 2010), the school was great about reviewing & updating. Now, schools are scrambling to enroll top students, so it’s quite possible that they might be willing to bend their own rules if they think a student is worth it.
