Transferring

Got accepted as an incoming freshman to the College of Engineering, but ended up at Texas A&M. Looking to apply to transfer in Fall of 2016, but there are a lot of pre-requisite courses that I would have to go to summer school to take and would not have credit for when applying. Do they look at what you will have completed by the time you attend? Also what would you say chances of getting accepted are assuming I already got accepted as a freshman, double legacy, 30 act, 3.8 hs gpa, and around a 3.5 college gpa?
