How should I choose a major when applying to UC San Diego?

At UC San Diego, the smart way to choose a major is to balance genuine interest with how selective the major is. You do not need to have your whole career figured out before applying, but you should apply to something you can honestly support through your classes, activities, and interests.

A big thing to know is that UCSD has capped majors. These are majors with limited spots, and admission to the university does not guarantee admission to that major.

So if you are seriously interested in a capped major, it is usually better to apply to it from the start rather than assume you can switch in later. On the other hand, if you are unsure and your interests are spread across different fields, choosing a non-capped major that still fits your academic story can give you more flexibility once enrolled.

You should also look at UCSD’s departments and major requirements now. Read the lower-division courses for the majors you are considering and ask yourself which classes you would actually want to take. That is often a better guide than choosing based on job title alone.

If you have a few interests, try grouping them. For example, if you like biology, public health, and psychology, think about which one you would be most excited to study deeply for at least the first year or two.
