As a female, your acceptance rate will go up at quite a few schools, including Georgia Tech, where female acceptance rate is one and a half times male acceptance rate. Being below the top 10% at your school may be an issue even in state for Georgia Tech. Taking distance math will help. The Georgia Tech website publishes an admissions snapshot which will tell you where you stand with respect to admitted students from your school Please note that this is a five-year snapshot so last year’s average will be higher in all likelihood than the five-year average HomePage | LITE - Leading Insight Through Empowerment
Typically, in state Georgia students are more likely to get into Purdue than Georgia Tech so I would not classify both of them as likely. Given your class rank I would put Georgia Tech as a tossup, even though you should get a significant boost being female. I would also move UIUC to toss up as it is typically a harder admit than in state Georgia Tech for engineering.
Definitely consider Embry Riddle. We know several kids who graduated from there and have gone on to great jobs and graduate schools. I would also put Auburn on your list. It has a strong engineering school, is about the size of Georgia Tech, and always has some of the happiest college students. Between my two Georgia Tech kids and their multiple internships (we are at 6 now and counting) there always seems to be an Auburn engineering student in their cohort. Definitely apply by early September for the best chance of admission and scholarships.
