UT Austin CAP Program for bio major?

I have been offered the CAP program for UT Austin. I plan on accepting, but after reading certain discussions on it, I am not sure. I understand that you can only get automatic admission after one year into the Liberal arts program, but I am planning on majoring in biology. How hard would it be for me to accept the CAP and get into the school of natural sciences after one year? Am I bettered off accepting at another four year university? Or should I call admissions and ask for more specific details? Any info would be greatly appreciated.

@kmc1234 I think you have posted in the wrong thread. This is the thread for TAMU. People in the UT Austin thread would be able to give you a better answer to your question.
