That chart is for a computer engineering major (with a cs focus) and not for a computer science major. It is also for holistic review students who had below a 3.5 cumulative GPA. See Thelma2’s post #1 for the CS link if your son is a CS major.
There are 2 different GPAs shown on your link. The top is the cumulative GPA. The bottom is the GPA for only the math, science, and engineering classes.
A student could have a cumulative GPA below 3.5 (due to lower grades in English or history classes, for example) but have above a 3.5 GPA in only their math, science, and engineering classes.
It makes sense that kids who gravitate toward engineering would have higher math and science scores but possibly lower language arts scores. I’m sure that’s one thing they evaluate during the holistic review process.
Here are the ETAM requirements for the class of 2022. The cumulative GPA must be 2.0 or above, with a 3.5 qualifying for automatic entry to your major https://engineering.tamu.edu/academics/entry-to-a-major/general-engineering-program/index.html
I hope that makes sense. One of the more experienced members may be able to explain it better!
