I agree with the previous posters. Premed is intense. Go to a college where you can graduate at the top of your class. A small liberal arts college would be a good choice, preferably one that will give you lots of aid.
If you can graduate college with a > 3.8 GPA, you are in good shape. The trend nowadays is for many premeds to take a gap year after college, and then apply.
The undergraduate college that you attend is taken into account, but won’t overcome low grades or MCAT scores.
