Sorry guys for the late reply. I couldn't log in due to technical reasons.
Thanks for your insight in choosing between Georgetown and USC. Actually, I was inclined to choose Georgetown because I thought I would have better chances in consulting there. However, I am offered an admission from Cornell at the end of May and I accepted this offer. So, I will be in Ithaca for the next two years.

This means, one more spot would be opened in Georgetown and USC.
Good luck to all wait listed applicants!
