Can you take a AP Art history or AP 2D Visual Arts/photography or a DE class involving urban issues/urbanism/cities?
In addition, you have to look at other colleges than TAMU, especially for architecture (note that it’s currently the major with the lowest salary prospects so look for colleges with full tuition scholarships, be they Ole Miss or UAlabama or Texas Tech…)
For TAMU, you have to be top 10% in your HS to have a good shot at having your major, and if you’re outside top 20% forget it.
Check out UT Dallas, Austin College, Southwestern, TCU, Hendrix: which do you like, which do you dislike? Why?
