TCU or Sam Houston State University? Or else where?

You could probably get into SHSU, and you should keep it in mind as on your list. TCU might be a little more challenging but not for the reasons of not much volunteer hours nor NHS. A lot is riding on your SAT scores and your GPA. You might want to check out Stephen F Austin in Nacagdoches.......nursing program has been around for quite awhile and is reputable.
