Is UT Austin or UC San Diego harder to get into overall?

For a regular applicant overall, UT Austin is usually harder to get into than UC San Diego, especially if you are applying from outside Texas. UT Austin has a very unusual admissions structure because Texas applicants in the top portion of their class can be admitted automatically to the university, which leaves fewer spots for everyone else. That makes the remaining review pool, especially for non-auto-admit Texas students and out-of-state applicants, extremely competitive.

UC San Diego is also a highly selective public university, but its process is more straightforward in the sense that everyone is reviewed under the same UC application system rather than having a large auto-admit group taking many seats first. For many students, that makes UC San Diego feel slightly more predictable than UT Austin, even though neither school is easy.

The student who often finds UT Austin tougher is someone applying from out of state, someone aiming for a popular major, or someone in Texas who is not in the automatic admission range. UT Austin can be especially difficult for majors like business, engineering, and computer science, where getting into the university is only part of the challenge.

UC San Diego can feel comparably hard for students applying to very in-demand STEM areas, and California residents still face serious competition. But in a broad overall comparison, UT Austin tends to be the more difficult admit for the average non-automatic applicant because of how constrained its available spaces are.
