I do believe that acceptance at a well -ranked law school would be more likely if you are applying with a degree from an elite college. The competition is tough at that level and you need to set yourself apart from the thousands of applicants coming out of mid-level public universities. Can you try to transfer into an elite public university instead of one that is attended by your friends? Chances are slim but it might be worth a try. I also love the idea of studying abroad or interning for a semester. Other than that, I’d suggest trying to stay unless you’re despondent and your health and grades are likely to suffer. The type of law school you get into could drive the direction of the rest of your life in dramatic fashion.
