My D was a total underachiever in HS. Despite having tested into the gifted program for K and (after we moved) attending an elementary school for gifted kids, she refused to take any honors or AP classes in HS and basically phoned in every class her first two years. In her junior year, she decided she wanted to teach and worked harder after that. She graduated with a 2.9 GPA. With no honors/AP’s, she had no weighted GPA. In college, she worked hard and graduated magna cum laude.
