Hey!! So I am a first year Pre-Nursing student at UT Austin. I'm in my first semester but I will be applying for the upper-division professional sequence in September. Basically I'll take classes in the winter break and summer and then be eligible to apply in September. The application process for the upper division is competitive as there are over 100 students applying for around 50 positions in the fall and 60-70 positions in the spring. They really look at GPA, volunteering experience, and your essay. The GPA is then divided up into the UT Overall GPA (which is all UT courses taken at UT), UT Science GPA (all science courses taken at UT), and you overall GPA. I have been told to keep at least a 3.3-3.5 GPA in order to keep competitive. Its sort of stressful in lower division, but from what I hear from upperclassmen, the upper division is really good... Hope this helps.
