It doesn't matter how well you do. If you don't have the college prerequisites, they won't let you in, end of story. My own experience, I decided to go to medical school after finishing undergrad. Took the MCAT and knocked it out of the park at 520 only to find out midwits wanted muh courses, muh volunteer hours, muh research experience, muh letters of recommendations. That would take over two years. Gave up on that dream like everything else.
