I’m curious as to where you got your info on GT and admissions. Has GT recently changed their admission policies? I thought they were one of the schools which did not admit based on intended major. I couldn’t find a 2015 statement confirming that though. This is from 2013: Our admission committee does not use your choice of major, as listed on the application, to make the admission decision.
According to the COE’s website, admission to engineering is through admissions:
