I'm confused about Texas A&M?

My Girlfriend and I want to attend the same college but we both have two different interests. We both like the university of Texas A&M but from what I can tell is that there are several campuses around the state of Texas. The major I am looking at is Mechanical Engineering. She is looking at zoology. I just want to make sure if we apply to the same university we will end up in the same place. If I'm correct we should apply to the college in College Station, Texas. Any help with this issue would be greatly appreciated.
