My son was in the same boat a few years ago… accepted to 2nd choice major at VT (1st choice COE), but accepted to every other good engineering school he applied to. You really have to go with your gut about which school you want to go to and how important the major is to you. My son had his heart set on his 1st choice school and got in easily, but it was OOS and expensive, with no financial aid. In the end we all just couldn’t justify the cost. And he was never wild about his other engineering choices, even though they were very good programs and he would have had no problem getting a job with an engineering degree from those schools. This is definitely a YMMV situation…
In the end he went to VT and eventually was able to transfer into COE. BUT it wasn’t easy - and it’s getting more difficult. It is not a sure thing and it was very stressful couple of semesters while he put the pieces together to make the transfer. The transfer requirements a well laid out in the website but essentially to transfer into COE youhave to take specific engr prereqs at VT and get a specific GPA - I think it’s a 3.2 now. That is not as easy as you’d think, many of these are pretty tough to get through with an A/B. And just getting into the classes can be a challenge, there aren’t a lot of open seats available in some and you have to be ready to grab empty seats as soon as add/change day starts - often at 1am. It wouldn’t be surprising if you needed an extra semester or so to finish. But it’s not impossible, you just have to understand the risk of taking this route. It’s also quite possible that you’d start out in your “new” major and find you enjoy it. If you’re close enough to VT to make another trip down, it might be worth it dto make an appt with your accepted major and see what you can learn about it. Does this major have a regular presentation day for perspective students?
Hope this helps a bit and best of luck to you!
