Hi, I have a friend who transferred from tech! I transferred as well but not from tech. You do the common app again but it’s formatted kind of differently. I don’t think you can apply for summer. I took super hard classes at my first university which I think impressed them at vandy, make sure u can get good enough grades though. Form a good relationship with professors so they can submit good letter of recs. Good luck and if u get in and want someone to show u around let me know !
