Are you being offered TAMUG while applying to TAMU, or you applied directly to TAMUG and got accepted, if so what major?
Engineering Academies at Blinn Brenham is in general a 2 year program. It is not the same as TEAB that offered to TAMU engineering applicants as TEAB is a one year ETAM program.
Engineering Academies still have similar engineering first choice option like ETAM, but students are required to stay on Blinn to finish Calculus I/II and III. Which at times, will need minimum 1.5 years to finish. (48 hours from Blinn Brenham and 9 hours from TAMU) LLC dorms are limited to Mill Creek Hall or Prairie Lea Hall.
