I've never heard of McOombs, but I would try to transfer into McCombs as fast as possible because you can start the business core classes your second year and it makes life a lot easier. You should definitely take the indicator courses as the above post says. Aside from that, take the governments and histories because very few classes give more than 15-20% A's for the core classes of those at UT and I've heard that they are easy A's at pretty much every other college in the country it seems. Everything else will be easier and probably give a higher A rate at ACC than at UT, but I think those would be the most dramatic aside from the indicator courses (which are some of the hardest lower-class courses at UT, especially the calculus!).
