Can you take Lower Division classes during your junior year at University of California campuses?

Yes, you can absolutely take lower division classes during your junior year at a UC campus. There's no rule preventing it. However, it's less common as most students aim to complete their lower division requirements by then and focus on upper division courses relevant to their major. There might be specific circumstances where taking a lower division course is necessary or beneficial, such as:

* Prerequisite: A junior might need a lower division prerequisite for an upper division course.

* Elective: Students might choose a lower division elective that interests them, even if it's not directly related to their major.

* Major Requirements: Some unusual majors might require a lower division course even in the junior year.

* Changing Majors: A student switching majors later might need to fulfill requirements with lower division courses.

In short, it's allowed, but not the norm. It's best to check with your academic advisor if you're considering taking lower division courses in your junior year to ensure it aligns with your degree progress and graduation timeline.
