Updated: August 27th, 2026
Welcome to the Fall 2026 Updates page!

Here you will learn: important Fall 2026 course information, how we manage the waitlists, enrollment priority information for CSE majors, when we are opening any available seats, and how non-CSE majors can request to enroll in CSE restricted courses.
Due to the high demand for CSE courses, enrolling in CSE courses can be difficult and confusing. Please read the following page in detail.
This page is periodically subject to change so we recommend checking our website and the Schedule of Classes for the most up-to-date information.
Important Notes:
-
Assume everything is in person and/or synchronous unless stated otherwise in the "Notes" below for the course section. Course components with the location listed as RCLAS on the Schedule of Classes via the Triton Student System will be remote/online courses.
-
If you are enrolled in a Summer 2026 course that is serving as a prerequisite for a Fall class, you will need to submit a Triton Enrollment Authorization (TEA) request in the Triton Student System.
-
Non-CSE majors: If you are submitting a TEA request for a Fall major restricted CSE course using a Summer 2026 course at UC San Diego as the prerequisite, please submit your request as early as possible. Your request will not be reviewed until mid September, when non-CSE major requests are evaluated after major enrollment. Although your request may appear pending, this is expected. Please do not contact the department for status updates or expedited review, as these requests will not be accommodated.

The CSE Department will be reserving seats in the following courses for the Fall 2026 Quarter:
- CSE-008A
- CSE-011
- CSE-029
- CSE-100
Note: Due to the transition to TSS, we will not be reserving seats for CSE-012, CSE-020, CSE-021, CSE-030, and CSE-101 for the Fall 2026 quarter. To best increase your chances of getting into these classes, we highly recommend making sure to enroll in these classes during your first pass booking window.
Review Process and Deadlines
-
If space is available and you meet all prerequisites, enroll directly in the course during your first pass booking window. If you successfully enroll, you do not need major priority.
-
If one of the eligible courses listed above is full, and you are a CSE or ECE-BS-001 undergraduate student, join the waitlist as soon as your second pass booking window opens.
-
After you join the waitlist for the courses listed above that will offer major priority, we will contact you via your UCSD email with additional instructions. There is no set timeline for when these emails will be sent, so you should monitor your UCSD email daily.
-
Your email will include a deadline. You must complete the requested steps and/or respond by the stated deadline. Failure to respond or take actions by the deadline will result in the loss of your enrollment priority.
-
Enrollment and available space cannot be guaranteed. If you are unable to enroll in your desired CSE course during Fall 2026, you may need to take it in a subsequent quarter.
Note: As part of UC San Diego's transition to the Triton Student System (TSS), the major priority process for the courses listed above has been temporarily modified due to current system capabilities. Because this is a new campus-wide system, you may encounter occasional changes or unexpected issues as processes continue to evolve.
We appreciate your patience and understanding during this transition. If you have questions or encounter any issues, please contact the CSE Undergraduate Advising Office via the VAC. We are committed to supporting you throughout this transition and will do our best to assist as we continue adapting to the new system.

If a student is not enrolled in enough units by the beginning of week 1, they should contact their department advisors via the VAC.
TEA requests for Late Adds in the CSE Department will be denied, so please plan accordingly.
Waitlisted Students
If you are on the waitlist for a class, you are expected to:
- Attend class for the first two weeks.
- Complete all course assignments during that time.
Important: Attending class and completing course assignments does not guarantee enrollment.
If you miss class meetings or assignments while on the waitlist and later secure a seat in the course, you will receive a “0” for all missed work.
CSE instructors are not directly involved with late add requests. Do not contact the course instructor regarding enrollment or late add concerns.
- Waitlist Policy

- Enrollment/Course Policies and Procedure
-
Classroom Capacity
The capacity in each course is determined by multiple variables (not just the classroom size), including but not limited to classroom size availability, instructor availability, instructor teaching load, instructional support availability (TA/tutor support), and scalability of the course.
TEA
For course clearances, please submit a Triton Enrollment Authorization (TEA) request in the Triton Student System. This may take 5 business days to be processed.
- Please note: some TEA requests, including those for special topics courses, require instructor approval before they can be processed. As a result, these requests may take longer that the 5 business days to be reviewed and approved.
Petitions
If you need to petition a course for transfer credit, please use our Online Petition to do so. Please view our CSE Petitions page for detailed information. This may take up to 6 weeks to be processed.
Prerequisites
Enforced for all classes.
View the Prerequisites for CSE Undergraduates page for information on all our prerequisites as it pertains to transfer courses and course substitutions.
Please make sure to carefully review our and our Upper Division Prerequisite Policy.
Swaps
No swaps - no exceptions.
Be sure to enroll or waitlist in the section with the assigned time you will attend and the assigned final exam you can attend. This includes R (remote) courses.
If a student is waitlisted for a course and then enrolls in the R version (or vice versa) or a duplicate version of the course, the system will drop you from the waitlist or will not allow you to enroll, because it recognizes you are already enrolled or waitlisted for the other course.
- We will not clear students to add to the course in these situations as the system moves on and automatically adds the next eligible student on the waitlist.
CSE instructors are not directly involved with student enrollment. Do not contact the course instructor regarding enrollment concerns.
- Non-CSE Majors and Major-Restricted Courses
-
Major Restricted Courses
Major-restricted courses are various CSE courses (indicated with an asterisk * below). Please see CSE Course Prerequisites webpage for information on which majors are approved for major restricted courses.
While these courses are restricted to CSE majors, non-CSE undergraduate students may still submit an enrollment request through a Triton Enrollment Authorization (TEA) request in the Triton Student System to be considered for enrollment.
Note: Major restriction is separate from major priority. Major priority is CSE's lower-division core courses, plus CSE-100 and CSE-101. Major restriction is select upper-division courses.

- Max Unit Exceptions
-
Max Unit Enrollment
During fall, winter, and spring booking, you can enroll in up to 11.5 units during the first pass.
During the second pass you can enroll in up to 19.5 units, including wait-listed courses.
Starting on Monday of Week 1 of the quarter, you may request a max unit exception via Triton Enrollment Authorization (TEA) request in the Triton Student System to enroll in more than 22 units.
Important Notes
-
When the college grants a unit limit exception it is for the course requested, not the quarter.
-
If a seat becomes available in a waitlisted class, the system will bypass students requiring a unit limit exception. The seat will be offered to the next student on the waitlist who is under the max unit limit. Student needing the unit limit exception will not be added because the available seat will be taken.
-
If a student wants to be added off of the waitlist, they would need to be under the max unit limit (enrolled and waitlisted courses combined) so the system can bring them into the course if a seat opens up (in waitlist order of course).
-
We will not approve requests to enroll in CSE courses exceeding the max unit limit if there is a waitlist. Please plan accordingly.
