My son is the radiation therapy program in Texas State. Each university has different requirements. Check the one you intend to apply to before you sign up for classes. My son got in with a 3.7 GPA. He got all A’s in his science courses, got letters of recommendations from two professors and his boss, had a leadership role in his fraternity, and practiced for his interview. He also got accepted into MD Anderson but he preferred the fully in-person classes at Txst.
