I believe that you have gotten answers to this specific question. We think that your academic profile is very strong, but the chances of successfully transferring to Columbia as an undergraduate student are bleak unless you can articulate a compelling academic reason that you want to make this transfer. You do not need to give us a compelling academic reason for the transfer, but you will need to articulate this to Columbia if you want to improve your chances of being accepted.
The two things that you can do to improve your chances would be to figure out what this reason is, and find people who will give you strong letters of reference to support your application.
