So… looking at UT’s site, things like regular old algebra and precalculus are not exactly generally required - they’re required if you’re not ready for the college level classes. Looks like at UT they require a single math class, and you can take things like data science or a regular calc class. There does appear to be a couple basic history classes required, but after that, you have a choice of some electives that I’m sure aren’t high school equivalent. So if you have 2 years of high school classes, uh, yeah,.you’re either doing a lot of remedial work, or purposely sandbagging.
IIRC, you previously defined reasonable as 13 hours - that’s the MINIMUM required to be considered full time. Sorry, but no.
A whopping 6 hours of English comp and core writing is required. Most people would be well served with more.
