Welcome to the General University Academic Center (GUAC) web site. Texas Southern University ( TSU) strives to be a viable, wholesome, responsive academic community for all its students, but particularly for first-year and transfer students. Central to this process are a strong academic advisement component and effective academic support. GUAC staff continuously seek new and creative support programs appropriately suited to the needs of students as they fulfill their Texas Higher Education Assessment (THEA) and ASSET obligations.
