Confused Boomer, Help Needed Please

[LevelUP]

My ultimate goal is to earn a B.S. degree then go on to GT OMSA/UT Austin’s M.S. in D.S./UC Boulder’s M.S. in D.S.

I realize I most likely have absolutely no chance with GT or UT Austin so UC Boulder may be my first choice by default.  
Thanks

A BA degree is just as good as a BS degree. This won't make much difference with employers or grad schools.

Plenty of people have transitioned from TESU/PUG/WGU to GT. Your past grades won't be on your TESU transcript, and though a grad school could request your previous grades, it's still possible to gain admission to prestigious grad schools.

A computer science degree is the best option and would be much easier than pursuing an IT or Data Analysis degree at TESU.
