Since you are a student, you might start here:

The pertinent part (albeit vague):
Use or possession on campus of ammunition, firearms, explosives, or other objects that are dangerous or flammable or that could cause damage by fire or explosion to persons or property. Firearms are prohibited in or on any portion of buildings, grounds or parking lots except as allowed under Subchapter of the Texas Government Code. Felony status and penalties for breach of state law apply.
Notice that they don't cite the specific subchapter of the TGC. They don't want to give us stupid CHL holders any hint to the section of that code.
ahem...cough...Chapter 411, Subchapter H...cough....
Texas Penal Code 46.035 will define premises for you:

In my case, I am a college employee. I can't be arrested for having my sidearm locked in my vehicle on a college parking lot, but I could be fired.
