Dartmouth is more of the same as with UNC. It has a 5% acceptance rate and has to be considered a reach for anyone.
Maryland accepts half of its in-state applicants. That’s the good news. The bad news is that 91% of this freshman class had a high school gpa of 4.0, a mark you fall just shy of. The rest of your application appears to be strong, so I would expect your application to be a toss up. As @thumper1 said, get your application in early because they take a high percent of their freshman class off the Early Action list. I only know one student who applied to U MD. He was a strong candidate and was accepted but he was rejected for engineering, so some majors seem to be more competitive than others. Fortunately you’re not applying to engineering.
Best of luck with the process.
