How do I get into Columbia grad?

<p>can someone please help me out. I am currently supposed to go to SUNY Stony Brook University. This university is known for pre-med and what not. if I attend this university I will pay $20,000 for the 4 years. Until recently the recession hit my family and therefore getting those $20,000 is hard and I am now considering CUNY Queens college. Queens is a public city college where I wouldnt pay for anything. Should I invest and take lowns for Stony Brook University or should I go to Queens College. My dream school is Columbia University Medical School. Another school I would hopefully wish to attend is Mount Sinai Medical School. Which the school affect my chances at med school? Please any help is apreciated.
Thanks</p>
