Should I continue with Columbia's wait-list offer?

So I have a tough decision to make and I really need some insight.

I have been wait-listed from Columbia University but I did get accepted to University of Pennsylvania. Should I bother writing an appeal letter and continue waiting for Columbia’s decision or should I just go through with Penn? How likely are applicants in the wait-list pool to be accepted?

There are usually a few applicants, sometimes a few dozen accepted off the wait list of several hundred every year.

It is worth it for some, but not for most. So don’t get your hope up.

Best wishes and great success to you at Penn.
