My son is thinking about switching majors after fall. Is winter quarter a smart reset or does it mess up sequencing so badly that summer becomes mandatory to catch up
Switching majors after the Fall quarter at UC San Diego can be advantageous if done early, as most major changes are processed automatically before reaching 90 units. However, the impact on course sequencing is significant and varies based on the nature of the new major.
Course Sequencing Considerations
- Many STEM and specialized majors, such as Engineering and Bioengineering, have strict prerequisite chains that often begin in the Fall. If your son switches to one of these majors in Winter, he may face delays in his graduation timeline, possibly extending it by a full year if key courses are only offered annually.
- If he misses a Fall prerequisite, he may need to enroll in Summer Session classes to catch up and remain on track for the standard graduation limit (12 quarters for first-years, 6 for transfers).
- For selective majors, students typically cannot switch immediately in Winter. First-year students usually must wait until Summer 2026 to apply, while some majors like Mechanical and Aerospace Engineering may allow applications during Winter 2026 for first-year transfer students.
