Expunging a grade is high school

I have gotten two D’s and two C’s throughout my high school career and I wanted to apply for a scholarship that you can only have A’s and B’s. My first thought was I can retake those four classes but then I realized it said that I can only retake up to three classes. My high school requires three science credits and I have 4 1/2. Luckily one of the classes I got a bad grade in was a science class. I was wondering if I would be possible to expunge that one grade so I could apply for this scholarship. It’s a great scholarship that covers 100% of tuition.

You have to talk to your high school, no one out here could answer that question.
