My daughter is a freshman at UT. She was auto admit and her portal changed to “accepted” and she received a banner and acceptance letter in the regular mail in mid-October. (I have a picture of her holding the banner dated Oct 17). The portal updated saying accepted to UT but she had to wait until Feb. 1, to get accepted into her major. This was the same for every one of her friends. I know several waves went out before Feb. 1, where some people were notified of majors earlier, but I believe the vast majority were not told until Feb. 1. (I’m not sure if certain schools notify earlier. Most of her friends are in CNS).
Feb 1, was very stressful. We must have ‘refreshed’ the screen a thousand times! She was accepted to her first choice in CNS.
Good luck to you both!
