Has anyone else here applied for the LLM at Cornell University?

I have applied and sent my application in October.

Cool when do we actually hear back from them, do you know?

I expect to hear from them in February (an optimistic expectation:)

Do you know if Cornell uses a rolling admission system?

I read somewhere that they do, but I might have mixed them up with another University.

Yes, they use rolling admissions system. Because I remember that some people from this forum received their admission mails before the deadline.
