Thanks for the advice everyone.
This whole process can produce so much self-doubt.
I don't know the pre med advisor at all. As I said before, I took all the pre-reqs as post bacc evening classes. My post bacc grades are fine but my undergrad scores are terrible. I also bombed the MCAT. I want to apply but I don't want any further discouragement from any advisor. I had one advisor already tell me before taking post bacc classes that I had a terrible shot at getting into med school, that I didn't want to hear it again from someone else.
With my poor MCAT scores, I was all set to try again next year but then I got a few secondaries and decided to try my luck. Which brings me to where I am now, and it's already late in the game. Most of the schools will accept LORs without an advisor's letter.
I might just follow your advice and see what my advisor has got to say. I need all the help possible and maybe the extra push of an advisor's letter will be sufficient.
Thanks again.
