CAP Program at UTSA

Hi, I’m taking CAP program at UTSA and planning to transfer to UT Austin with the major of computer science.
But I learned that the CAP program offers automatic admission into UT Austin for only majors of liberal arts.
Does that mean I have to compete with other transfer students to get into UT Austin with the major of computer science? Is it hard to get into UT Austin with the major of computer science?
Also, can I take a leave of absence during the CAP program?
I will really appreciate it if you can answer them!
