My DT just graduated from GT in Dec. and one of her closest friends graduated in May as the #1 graduate in the EE dept. I just had hand surgery so I can’t write more until tomorrow but search under my name and you can see my previous posts about GT.
I also disagree with poster. Class size at GT is small other than a couple intro classes and advising is very personal and top notch!! If you subtract co-OP or internship time away from campus, my Dd and all her friends graduated in 4 years. All work with top companies and had a great college experience.
Two students from my dad’s first robotics program went to Penn and IMO DD had a more diversified e experience. (E.g. study abroad, completion teams, sports, social justice etc).
You can switch majors once no questions asked and then I think a form and some approvals afterwards.
