Winter 2022 Enrollment

Course Prerequisite Clearance Form:

If you completed the prerequisite for a Bio Sci course outside of UCI or via AP credit, you will need to submit a Course Prerequisite Clearance Form to be cleared for enrollment. You DO NOT need to submit a form if you are currently enrolled in the prerequisite of a course you will take in the winter.

Examples of students who need to submit a form:

  • Transfer students who completed Bio Sci 93-99 equivalent courses at a community college.**
  • Students who earned a 5 on the AP Biology exam and waived taking Bio Sci 93 and/or 94 at UCI.

The form does NOT override major or repeat restrictions. If you are not a major that requires the Bio Sci course you are requesting to enroll in, or if you are attempting to enroll to repeat the course, you will be held to the major and repeat restriction lift date and your request will be processed to be ready at that point.

The form can be found HERE. 

Important Dates
