OP, talk to one of your advisors in your major about your shot at grad school. You’ll need their support. It’s not open season like undergrad, where you just apply with a major in mind and, once admitted, figure it out as you go.
But first, do some research into the basics. Your college GPA is your college GPA, not what you did in high school. DE is a high school program, shows on the hs transcript.
Why would a law or medical school be interested in high school grades? Since @mnsch1 mentioned Texas A&M, the law school asks for “all post-secondary transcripts”. You can find that online, I did. All college courses/grades since high school.
Let’s get on the right page.
