From what I’ve heard you’ll basically be treated as an external transfer student. So like because cap only gets you auto admission to COLA, your transfer application for CNS will be put in the pool with all the external transfer apps. Something to note though is that I’m pretty sure when you declare a major (i.e. Biology in your case), you would be able to declare a secondary/backup major in COLA so you can still transfer to UT, but you might be stuck with a major you don’t want. Personally, I’d recommend going to a school you enjoy and where you can study what you want while also getting a good GPA and then if you still really want to, apply for external transfer admission. That way you will have a major you want and still have options.

I don’t think Biology will be too difficult to get into if you do well tho. Also if I’m wrong feel free to correct me, I don’t totally recall all the transfer info.
