Spring 2025 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.
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 just before the restriction lift date and time.
Prerequisite clearance will remain in place for Dunlop School 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 10.
Bio Sci Overlapping Course Policy:
Bio Sci will not allow students to enroll in classes with overlapping times; students need to ensure they do not enroll in classes that have overlapping final exam periods.
Bio Sci Lab Enrollment Policy:
All Bio Sci labs (courses with an L suffix) and Bio Sci 100 have an early drop deadline of THURSDAY, MARCH 27 at 5PM. Students cannot swap/change their lab section after the early drop deadline. Students may add open Bio Sci labs through the first meeting of the lab. After the early drop deadline, students should contact biosciadvising@uci.edu for assistance enrolling in open labs.
Upper Division Bio Sci Lab Enrollment Procedure:
Bio Sci has introduced a new process to better prioritize lab enrollment for Charlie Dunlop School of Biological Sciences seniors who are closest to graduation. Bio Sci will prioritize enrollment in upper division labs by pre-approving all Bio Sci students who can reasonably graduate in the next few quarters (Spring 2025, Summer 2025, Fall 2025).
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 7 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 Monday, March 10 at 7:00pm, Bio Sci lab sections that were initially restricted to specialized majors will open to all students in the graduating senior priority group (Bio Sci & BME: Premed).
- Bio D111L, Lab 3 (L-restricted for Developmental and Cell Biology, Genetics, and Biomedical Engineering: Premedical majors ONLY)
- Bio M118L, Lab 4 (L-restricted for Biochemistry & Molecular Biology and Microbiology & Immunology majors ONLY)
- Bio M121L, Labs 1 & 2 (L-restricted for Biochemistry & Molecular Biology and Microbiology & Immunology majors ONLY)
- Bio M128L, Lab 1 (L-restricted for Biochemistry & Molecular Biology and Microbiology & Immunology majors ONLY)
- Bio N113L, Lab 6 (L-restricted for Neurobiology majors ONLY)
On Thursday, March 13 at 12:00PM, 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.
On Thursday, March 20at noon, upper division Bio Sci labs will be open to ALL students that meet the prerequisites.

***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 Winter Study List. Ex: A Spring 2025 graduating senior wants to take Bio E79L with Bio E179 in Spring. Once the student enrolls in Bio E179, they contact Dunlop School chat or biosciadvising@uci.edu for Bio E179L clearance.
