First of all, if you're getting a MS in computer engineering, don't do med school. The laziest computer engineers I know at least makes around 6 figures.
Your life will be better.
otherwise,
1. Fix the GPA (Get sGPA as high as you can. AT least 3.0+)
2. Take prereq classes and get A's in all of it
3. Do volunteer/clinical
4. MCAT try 505+
5. Apply only DO. MD is far off. And apply to any and all of the DO including the new schools.
