One other point is that there are requirements to do ETAM and even if you have a GPA over 3.5 but you do not have for example both Math classes at TAMU yet, they will not let you apply for ETAM. So at the next opportunity for ETAM, the GPA in this case will be over 3.5 but the student has to go through the holistic process for review because auto admit is only for the first opportunity of ETAM.
The chart at Thelma2’s link above reflects the kids who went through the holistic ETAM process last Spring 2017, which is the class that entered in the Fall 2016. TAMU has not publicized the results of ETAM this past Spring 2018 for the class of Fall 2017 as of yet. From what I understand from TAMU advisors the stats do not paint a pretty picture for some of the majors and they made some changes to the ETAM process because of it. Apparently, some of the most popular majors including Computer Science and Mechanical Engineering were completely filled up with auto admits and could not admit anyone else holistically.
