I’m trying to find the source, but I don’t think your high school grades & GPA during COVID won’t result in your enrollment being rescinded. Most high schools also stated your grades will not go down before schools shut down, but you can raise your grade. My daughter also took a dual enrollment class at the CC and they sent a note that she can challenge her grade if she thinks it was lower because of having to do her class via distance learning.
