*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 D111L, Lab 7 – Genetics, Developmental & Cell Biology, and Biomedical Engineering: Premedical majors
Bio Sci E166L – Ecology & Evolutionary Biology majors
Bio Sci M114L, Lab 5 – Biochemistry & Molecular Biology and Microbiology & Immunology majors
Bio Sci M116L, Lab 3 – Biochemistry & Molecular Biology and Microbiology & Immunology majors
Bio Sci M118L, Lab 9 – Biochemistry & Molecular Biology and Microbiology & Immunology majors
On July 27th at noon all lab sections will become available to the rest of the graduating senior priority group, as long as they are approved for their current major.
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 2023 (or earlier) freshmen
Fall 2025 (or earlier) transfer students
Any Dunlop School of Biological Sciences student with a REASONABLE graduation application on file
At the beginning on Week 7 (May 11th), these students will automatically be pre-cleared pre-cleared for the labs that are approved for their current major if they meet the prerequisite.
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, at the beginning of Week 7 (May 11th) you will automatically be pre-cleared for all the labs that are approved for your current major if you meet the prerequisites.
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.
As long as students meet the prerequisites, they can enroll in additional labs on the following dates:
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.
Other Course Enrollment
Restriction Codes:
A – Prerequisite required
B – Authorization required
C – Fee required
D – Pass/not pass option only
L – Major only
N – School major only
O – Non-school major only
X – Separate authorization codes required to add, drop, or change enrollment
All Bio Sci labs (courses with an L suffix) and Bio Sci 100 have an EARLY add/drop deadline.
Bio Sci labs (specialized majors) – July 27th. Other restrictions will still be in place, please check our “When will I be able to register for labs?” section for more details.
Bio Sci D137, Dis 2 – July 31st. Initially reserved for Developmental & Cell Biology and Genetics majors.
Bio Sci E106, Dis 5 – July 31st. Initially reserved for Ecology & Evolutionary Biology majors.
Bio Sci M114, Dis 1 – July 31st. Initially reserved for Biochemistry & Molecular Biology majors.
Bio Sci M124A, Dis 1 – July 31st. Initially reserved for Microbiology & Immunology majors.
All Bio Sci courses – September 1st.
Specialized major decisions will be sent in mid-July, so students will be able to enroll in the L-restricted classes before the restriction lifts on July 31st.
You should note the course meeting time and leave that slot available in your schedule, so you can easily add the course(s) in July. Students do not need to be enrolled in 12 units, to meet the full-time requirements, until September 15th.
All students will be able to enroll in any Bio Sci course they meet the prerequistes for starting on September 1st.
Every Fall, some seats are reserved for students enrolling at UC Irvine for the first time. You can see the number of seats saved for new students in the NOR column on the Schedule of Classes. Continuing students will be permitted to enroll in a course until the number of reserved seats remain.
For example, Bio Sci E106 has 90 seats reserved for new students. Once 156 students have enrolled, the status will switch to NewOnly. If a student drops and there are more than 90 seats available, the status will switch back to Open and continuing students will be permitted to enroll again.
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 (StudentAccess → Student Profile → Enrollment → Course Eligibilities)
Repeat restrictions for all Bio Sci courses will lift on September 1st at noon.
The enrollment unit limit will switch from 18 to 20 units on September 1st at noon.
Students looking to enroll beyond 20 units will need to submit an Excess Units Petition by Friday of Week 2 of Fall quarter. The petition will open one week prior to the 18-unit lift date (August 24th).
Bio Sci 93 – September 1st
Bio Sci 97 – July 31st
Upper division Bio Sci courses – July 31st
The following courses will remain reserved for specific majors or programs throughout the enrollment process:
Bio Sci 2A – Incoming freshmen only.
Bio Sci 90L – Incoming freshmen and transfers only.
Bio Sci 190 – Incoming transfers only.
Bio Sci 197 – Contact the instructor for authorization.
Bio Sci 191AB – Global Sustainability minors only. Contact the instructor for authorization.
Bio Sci E117A – Exercise Science majors only.
Bio Sci N115A – Neurobiology majors only.
Bio Sci N120A – Human Biology majors only.
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 is managed centrally by Bio Sci Undergraduate Student Affairs and individual instructors cannot provide enrollment support (unless otherwise noted in the course comment box on the Schedule of Classes).
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 September 1st.
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.
Each host campus has their own deadlines for adding/dropping courses. If you need to drop a course, please follow the Dropping a Course instructions on the UC Online website.
