You can assume TTP is looking at first choice major. Major change impacts it in regard to what you should be taking prior to USC. You are able to communicate with your AO and will definitely get things laid out in the meeting over the summer as there are big differences in core between Viterbi and Dornsife. I would not be changing majors to a dif school with dif core requirements after the meeting, but the AO will certainly advise on that if something the student is considering.
