Easiest major at UT Austin COLA?

Hi,
I’m an engineering major from UIUC that wants to do econ at UT. I would be considered instate in Texas. I am still trying to figure out what I should put as my second choice major. I hear it’s really easy to transfer within COLA. My goal is just to get in at this point. I am looking at a worst case scenario gpa of a 3.4 and a best case to be 3.6ish but am on track for a 3.5. Any suggestions?
