TAMU ETAM statistics - #172 by pbleigh has some information on how selective each engineering major is at Texas A&M.
Bottom line is that if you want computer science or computer engineering or a handful of other popular majors, 3.75 college GPA is your target, because non-automatic admission to those majors is very unlikely.
However, some other engineering majors at Texas A&M have enough capacity to admit all interested students.
