A 2.0 is a "C" average. You are going to have difficultly getting in. Plus college is way harder and more demanding. Why do you have a "c" average? I don't want to take away your dream. I would find out where you'd like to go. See if you can speak with an admissions counselor. You might need to go to a community college first and show that you can get really good grades and have the self discipline needed. It will take a lot of hard work but is not impossible.
Well imo, the beat thing to do is do two years of community college and then transfer to University to complete the next two years or however many years you want you want to be there. A 2.0 is really low to get into a good college/university pursuing a degree in the medical field. With college experience and that gpa, you may have a better chance in transferring schools
