*The course can be taken as a prerequisite or corequisite. Students must first enroll in the corequisite course (appear in their Study List) before they can be cleared to enroll in the lab. Once this step is complete, please use the CHAT during our regular business hours to request lab clearance.
An L restriction is set for specialized majors. The following sections will initially be restricted for:
Bio Sci M116L, Lab 5 – Biochemistry & Molecular Biology and Microbiology & Immunology majors
Bio Sci M118L, Lab 7 – Biochemistry & Molecular Biology and Microbiology & Immunology majors
Bio Sci M121L, Labs A & B – Biochemistry & Molecular Biology and Microbiology & Immunology majors
On March 9th at 7:00pm all lab sections will become available to the rest of the graduating senior priority group.
Please see our “When will I be able to enroll in labs?” section to check when additional lab restrictions will lift.
For lab enrollment, we prioritize School of Bio Sci students who are closest to graduation, which we group under the following graduating senior priority group:
Fall 2022 (or earlier) freshmen
Fall 2024 (or earlier) transfer students
Any Dunlop School of Biological Sciences student with a REASONABLE graduation application on file
At the beginning on Week 7 (Feb. 18th), these students will automatically be pre-cleared for all the labs they meet the prerequisites for.
You can see if you have a graduation application by going to StudentAccess → Applications → Graduation.
For priority lab enrollment, your application status must read EITHER “pending” or “received”.
If you are part of the graduating senior priority group, you will automatically be pre-approved for all the labs you meet the prerequisites for at the beginning on Week 7 (Feb. 18th).
You can check lab clearances by going to 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, email biosciadvising@uci.edu at least 2 business days BEFORE your enrollment window.
Due to the high demand for upper-division labs, we recommend students submit their graduation applications 1 year in advance.
You can submit your graduation application on StudentAccess → Applications → Graduation.
If you meet all other criteria to be considered part of the “senior priority group” and submit your graduation application AFTER the start of enrollment, lab clearances will take 2-3 business days to process. You will receive an email once your lab clearances have been added.
If you are NOT part of the “senior priority group”, please see our “When will I be able to enroll in labs?” section to check when lab restrictions will lift.

The enrollment system does not automatically read courses taken outside UC Irvine. If you are trying to enroll in a Bio Sci course, please fill out the Bio Course Prerequisite Clearance Form. We will process your request within 3 business days. For non-Bio courses, you need to contact the academic unit offering the course.
BEFORE submitting the form please check your eligibility:
Repeat restrictions for all Bio Sci courses will lift on March 19th at noon.
The enrollment unit limit will switch from 18 to 20 units on March 19th at noon.
Students looking to enroll beyond 20 units will need to submit an Excess Units Petition by Friday of Week 2 of Spring quarter.
Bio Sci will NOT allow students to enroll in classes with overlapping meeting times, regardless of instructor approval. Students should also ensure they do not enroll in classes with overlapping final exam periods.
No, enrollment management is managed centrally by Bio Sci Undergraduate Student Affairs and individual instructors cannot provide enrollment support (with the exceptions of Bio Sci 197 and Bio Sci 191CW).
UC Online Enrollment
To be eligible to enroll in UC Online courses, UC Irvine students must:
UC Online enrollment requests take about 10 business days to process. Students must start the process as early as possible to ensure they are able to enroll in their intended courses BEFORE the start of the quarter.
The approval process first goes to the student’s major advisors (2-4 business days) and then to the Registrar’s Office (2-5 business days).
Students can verify they have successfully enrolled in the course once it appears on their Study List.
Yes, any UC Online courses will count towards your 12 unit minimum to be considered a full-time student.
Yes, any UC Online courses will count towards your initial 18 unit limit. This restriction will switch from 18 to 20 units on March 19th at noon.
Students looking to enroll beyond 20 units will need to submit an Excess Units Petition. Based on the processing timeline for UC Online enrollment, please be sure to submit this form at least 3 weeks BEFORE the start of the quarter.
It depends. Some UC Online courses MAY be used to repeat UC Irvine courses and replace previous grades, following our Repeat Policy.
However, students must FIRST receive approval from their major department. To request approval from the School of Bio Sci, please email biosciadvising@uci.edu.
Yes, Math 19A and Math 19B at UC Santa Cruz (through UC Online) are approved repeats for Math 2A/5A and Math 2B/5B respectively.
Grade replacement will follow our Repeat Policy.
