I have been an RN for 2 years and want to go to med school. I already have a strong science background. I am looking into post bacc. programs because I like the structure. I don't know if I would be denied acceptance to some programs because I already have taken many science courses. I was looking at the Harvard ext. school post bacc and it states that "As a diploma candidate, you may not have taken any of these courses previously at another institution." I don't really know if this means I cannot apply to this particular program because I have already taken some of the courses. I already have taken chemistry, physics, and biology so I don't know if acceptance in to these types of programs would be more difficult due to my science background. My other option is to finish the courses on my own. However, I would really like to go to a more prestigious school than my original undergrad at southern ct state university. Not to say it is a bad school, but I feel that graduating from Yale or Harvard would give me a better chance at getting accepted to a more prestigious med school, assuming I do well in my classes. Any input would be greatly appreciated thank you.
