Spring 2024 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 completed Bio Sci 93 in Summer 2023 or earlier and want to enroll in Bio Sci 93L. 

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.

Effective Spring 2023, prerequisite clearance will remain in place for School of Bio Sci students and will not be removed at the end of each quarter. Effective Fall 2023, incoming transfer students will be cleared for all courses that they’re eligible for. Students should check your existing clearances in StudentAccess under Course Eligibilities (Student Profile–> Enrollment–> Course Eligibilities) before completing the prerequisite clearance form.

The form can be found HERE starting Monday, February 11. 

Upper Division Bio Sci Lab Enrollment:

Bio Sci is introducing a new process to better prioritize lab enrollment for School of Biological Sciences seniors who are closest to graduation. Bio Sci will prioritize enrollment in upper division labs by approving all Bio Sci students who can reasonably graduate in the next three terms (Spring 2024, Summer 2024, Fall 2024).

During enrollment windows, pre-approved seniors will be able to enroll in labs that they meet the prerequisites for. Students can check their clearances beginning Week 6 in StudentAccess (Student Profile → Enrollment → Course Eligibilities).

If you believe you should have access to a lab that does not appear on your course eligibility list, contact biosciadvising@uci.edu prior to your enrollment window

On March 11 at 7:00pm, Bio Sci lab sections that were initially restricted to specialized majors will open to graduating seniors. 

On March 13 at 7:00PM, we will open lab enrollment to all Bio Sci students who meet the prerequisites for the lab. Additional authorization will not be needed if the prerequisite was taken at UCI.

Beginning March 20 at noon, upper division Bio Sci labs will be open to ALL students that meet the prerequisites. 

Upper Division Bio Sci Lab Prerequisites:

Bio Sci N113L***: Senior Standing AND Lower Division Writing AND (Bio 100 of Bio 108) AND (Bio N110 Or Bio N115A)

***Graduating students planning to enroll in a lab with a corequisite should contact Bio Sci Chat during business hours (Monday: 10am,-12pm, 1pm-4pm; Tuesday-Friday: 9am-12pm, 1pm-4pm) for Bio lab clearance, AFTER the corequisite appears on their Spring Study List. Ex: A Spring 2024 graduating senior wants to take Bio N113L with Bio N110 in Spring. Once the student enrolls in Bio N110 for Spring, they contact BioSci chat or biosciadvising@uci.edu for Bio N113L clearance.
