In the past two academic years, 29/49 and 36/53 applicants were offered admission. I wouldn’t say that’s “easy” since they have a hardline policy on requiring an engineering degree w/ physics minor or an actual physics degree. Other programs are a little more flexible with minimum requirements since CAMPEP only requires a physics minor. I live in a city with university that has an evening program that can be taken part time, but I’ll definitely be applying to GA Tech. It’s probably the only option for a lot of people.
