Winter 2025 Enrollment

Due to a technical error, the Registrar’s Office has pushed the reopening of WebReg to 12pm (noon) on Friday, December 20. All restrictions scheduled to lift on December 19 will now lift Friday, December 20 by 12pm. 

When WebReg reopens on December 20, graduating senior priority will be back in place for upper division Bio Sci labs. Only students that had access during their enrollment window will be able to enroll. Graduating senior priority will not lift for Winter 2025. 

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, November 4. 

Bio Sci Lab Enrollment Policy:

All Bio Sci labs (courses with an L suffix) and Bio Sci 100 have an early drop deadline of FRIDAY, JANUARY 3RD at 5 PM. 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 year (Winter 2025, 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 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 Monday, December 9 at 12:00pm, 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). 

  1. Bio D111L, Lab 9 (L-restricted for Developmental and Cell Biology and Biomedical Engineering: Premedical majors ONLY
  2. Bio E112L, Lab 12 (L-restricted for Exercise Sciences majors ONLY)
  3. Bio E115L, Lab 1 (L-restricted for Ecology & Evolutionary Biology majors ONLY)
  4. Bio M114L, Lab 4 (L-restricted for Biochemistry & Molecular Biology majors ONLY)
  5. Bio M116L, Lab 1 (L-restricted for Biochemistry & Molecular Biology and Microbiology & Immunology majors ONLY)
  6. Bio M118L, Lab 10 (L-restricted for Biochemistry & Molecular Biology and Microbiology & Immunology majors ONLY)
  7. Bio N113L, Lab 10 (L-restricted for Neurobiology majors ONLY)

On Friday, December 13th 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, December 19 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 D111L***: Senior Standing AND Lower Division Writing AND (Bio 100 or Bio 108) AND ((BIO D103 OR Bio D104 OR Bio D105) OR 

Senior Standing AND Lower Division Writing AND Bio 100 AND (Bio D103 (coreq) or Bio D104 (coreq) OR Bio D105(coreq))

Bio Sci E112L: Senior Standing AND Lower Division Writing AND (Bio 100 of Bio 108) AND (Bio E109 or (BME 120 and BME 121)), No PHRMSCI 120L

Bio Sci E115L: Senior Standing AND Lower Division Writing AND Bio E106  AND (Bio 100 or Bio 108)

Bio Sci E131L: Senior Standing AND Lower Division Writing AND (Bio E106 or Bio E109) AND (Bio 100 or Bio 108)

***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 D111L with Bio D103 in Winter. Once the student enrolls in Bio D103, they contact Dunlop School chat or biosciadvising@uci.edu for Bio D111L clearance.
