Is UC San Diego or Tufts generally harder to get into?

The biggest practical difference is that Tufts is typically tougher overall because it has a smaller entering class relative to a very large, national applicant pool, while UC San Diego’s difficulty can shift more sharply by residency and major. Both are highly selective, but Tufts is commonly viewed as the more difficult admission on a broad, school-wide basis. UC San Diego is still far from a safety, particularly for applicants seeking engineering, computer science, or other high-demand programs.

Tufts uses a private-college, holistic review that places substantial weight on academic preparation, course rigor, activities, writing, recommendations, and institutional priorities. Its applicant pool is self-selecting and academically strong, so excellent grades and scores alone do not make admission predictable.

UC San Diego evaluates applicants under the University of California framework and does not consider demonstrated interest. California residency, the academic context of the high school, and the intended field can meaningfully affect the practical level of competition. Some majors have limited capacity or separate selection processes, so an applicant pursuing a particularly impacted program may find UCSD comparable to, or in some cases more difficult than, Tufts for that specific path.

For an applicant without a narrowly constrained UCSD major, Tufts is generally the harder school to get into. Treat both as reaches or high reaches unless the rest of the application is exceptionally strong in the context of each institution’s applicant pool.
