Can I go to CSI for pre-med?

I was not a high academic achiever all through out high school due to the fact that I despised my school. However, I do believe I have the potential to someday become a doctor. So, my h.s GPA isn't all that great and neither is my SAT score (I first took it in June and will take it again). I am dying to go to Hunter but I've heard admission is competitive and I feel my chances of getting accepted is slim. So, other schools I have in mind include CSI, Brooklyn College and City College Any advice on what I should do or where I should go? I still have my heart set on Hunter, so how can I improve my chances on getting accepted there? Will teacher recommendations help? How about CSI and the other schools I listed? Are those any good for pre-med? If I get a above average college GPA and do well on MCATS, hopefully I'll go to NYU. Any thoughts/suggestions and all responses are greatly appreciated!
