Thank you very much for your reply!
As you know, I am an international applicant, so my english is not well enough as a Teaching Assistant. It is really a pity. Furthermore, I cannot be able to work in companies, such as Boeing, Lockheed. The reason is also that I am an international student
After Purude & UIUC, i got other two admissions, AE @ UT-Austin and ME @ USC, also no fundings.
So what about Austin, when compared with Purdue? Which one do you think is better?
