I think you are a solid applicant at Columbia. You would have good chances without ED; you’d probably be a low reach, but with ED I would consider you a match. Being Asian may hurt you a bit, but it won’t be the deciding factor. With your scores, I am confident that you will get in. Use the ED on Columbia. Good luck!
