FAQ
Reader questions
How do I choose between Computer Science, Bioengineering, and Political Science if I am undecided?
Start by mapping your interests to day-to-day work: if you enjoy building software and solving abstract problems, try CS; if you want to apply engineering to health and biology, explore Bioengineering; if you are drawn to policy, institutions, and research questions about society, Political Science is the stronger fit.
What kind of internship opportunities are available for each major during freshman and sophomore years?
CS students often secure software engineering or product internships at tech firms; Bioengineering students find roles in med-tech startups, research labs, and hospital departments; Political Science students commonly intern at government offices, nonprofits, campaign offices, and media outlets in Los Angeles.
Do these majors require advanced coursework in high school, such as calculus or computer science, to be competitive?
While prior experience can help, UCLA focuses on readiness rather than advanced placement; strong performance in challenging high school courses and clear intellectual curiosity matter more than specific prerequisites.
How easy is it to switch into these majors if I change my mind after starting at UCLA?
CS and Bioengineering are impacted majors with limited enrollment, so switching may require completing specific prep courses and meeting grade thresholds; Political Science generally has more flexible entry, but students should consult an academic advisor early to plan their pathway.
