My S is at Tulsa, and of his six suitemates, 5 are engineering or physics majors and all 5 had GPAs of 3.3 or higher first semester. They also are all division 1 athletes, so they are quite busy. I would say if you qualified for such a great scholarship, you are also capable of keeping the GPA. Good luck! Feel free to PM me with other TU questions. It is a GREAT opportunity.
