Enrollment Guidance for Physics Majors
This page will be updated the day the schedule goes live for the upcoming term and throughout the enrollment period. Please refer to this information before seeking personalized guidance. Be sure to read General & Term-specific guidance to know special options and how to use PASS 1 vs PASS 2.
Enrollment Steps
STEP 1: Check your degree audit and then check your official qtr-by-qtr plan for major-related courses for the upcoming term. See:
- Standard Plans
- PY29 Students: Please remember that you've been moved to the new curriculum in which PHYS UD Depth courses are now PHYS UD REs as shown on your degree audit.
- Alternate Plans
- VAC (for personalized plans for graduation provided/approved by the Physics Department due to you not being on one of the plans above)
STEP 2: View General Guidance, below.
STEP 3: View Term-Specific Guidance, below.
STEP 4: View the schedule in WebReg and adhere to the UCSD Enrollment Checklist.
General Guidance
The following guidance applies every term. Be sure to also read the Term-Specific Guidance, below.
Important Reminders
Review the Department comments below the qtr-by-qtr section of your plan to understand all major requirements and recommendations for your major.
Review the Informal Exceptions to the Major Requirements so you know about expanded PHYS UD Lab options and courses that have been renamed and/or renumbered within and outside of PHYS but can still apply to the major.
Remember, most PHYS courses are offered only once a year and prerequisites are strictly enforced. Enroll according to your department-provided plan to ensure timely graduation. If you cannot follow a posted/provided plan, immediately contact Physics via the VAC to request a personalized plan.
Ensure you have full-time status at the start of PASS 2 to meet campus requirements. Consider backup courses in case of scheduling issues. If you need part-time status, complete the application by the campus’ part-time status application deadline.
Majors/Specializations
Enrollment is a perfect time to check to make sure you’re in the best major/specialization to suit your goals related to physics. Click here to explore the majors and specializations in the Physics Department, along with their requirements. Click here to see checklists (only lists of major requirements) and frequently asked questions about the major and quarterly planning.
BA degrees in General Physics: Suitable for industry-bound students who want to tailor upper-division coursework. BA degrees avoid advanced theoretical courses (PHYS 105A, 130B, 140A), allows more electives, and typically takes less time.
BS degrees in Physics: For students aiming for graduate studies or technical careers. BS degrees require advanced courses and has fewer electives, usually taking longer to complete.
B.S. specializations do not enhance competitiveness for graduate school or industry. Students currently enrolled in a BS Physics major w/ a specialization may consider switching to the standard BS Physics degree (PY29) to receive the greatest flexibility in course selection within and outside of the Physics Department.
Major Regulations
Be sure to adhere to all Physics Department major regulations.

Scheduling PHYS Major Requirements You Must Self-Select
Remember that you’ll use our Annual Schedule of Physics Course Offerings and our course descriptions w/ prereqs to schedule physics major requirements you must self-select (eg. PHYS UD RE, PHYS UD DEPTH, PHYS UD LAB, etc.).
Prerequisites for Physics Courses & Pilot Prereq Alternatives
Prerequisites are strictly enforced (see policies here). If you don’t meet them, you cannot enroll and may need to select a different plan (see STEP 1, above). Please note the current pilot prereq changes in place:
Pilot Prereqs are used to test potential formal changes. In most cases, prereq changes will typically be piloted for several years before any changes are seen in the campus system (official changes are not guaranteed).
An EASy request is required to have the exceptions applied: easy.ucsd.edu
Keep in mind that, campuswide, corequisites are NOT enforced (no request is required for this to apply).
Term | Course | Pilot |
FA22-SP26 | 2DL | Combo of ECE 35 + 45 replace PHYS 2CL prereq |
W23, W24, W25, W26 | 152A | All students with prior completion of PHYS 4A-B-C-D-E and 100A and 110A may enroll. |
SP23, SP24, SP25, SP26 | 120 | All students in 4E or beyond may enroll, provided PHYS 2CL has also been completed |
FA23, FA24, FA25, SP25 (170) | 175, 170 | Upper division standing AND completion of lower division physics series (Phys 1, 2, or 4) AND (Chem126 or 131 or 132 OR an upper division / graduate biophysics course (Phys17X or 27x) or a 4-unit PHYS 199 under a biophysics faculty member (with recommendation)). |
FA25 | 116 | ASTR 102 can replace PHYS 100B; ASTR 101 can replace PHYS 110B |
Room Changes (for courses that are over or undersubscribed)
Starting during PASS 2, the campus can (and does) change the room a course is assigned based on enrollment numbers. For this reason, PHYS majors are advised to follow our enrollment guidance to ensure their seating in major requirements. The waitlisting and unit limit exception info. on this webpage is important to keep in mind.
Waitlisting
You can only waitlist a course once your PASS 2 begins. The PHYS Department monitors waitlists and tries to increase class sizes. Departments cannot guarantee that sections/seats can be added and no one in Physics can guess your chances of making it off a course waitlist.
Enrolling in Graduate (GR) Level Physics Courses (200-500)
See the Prerequisites section of the Enrollment Policies for eligibility and timelines for submitting EASy requests. Requests that are ineligible and/or are submitted too early will be denied.
Clearance to Enroll
For Undergraduate Courses: Submit enrollment clearance requests through the Enrollment Authorization System (EASy); email requests or VAC messages will not be accepted.
For Grad Courses: See the Prerequisites section of the Enrollment Policies for eligibility and timelines for submitting EASy requests. Requests that are ineligible and/or are submitted too early will be denied.
Unit Limit Exception Requests
Do not use unit limit requests for major requirements. Enroll in all major requirements by the first day of PASS 2 to ensure no delays in graduation (eg. if a class is full by day 1).
Course Conflicts
Avoid enrolling in courses that conflict; instructors are not expected to accommodate students who have schedule conflicts.
Independent Reading/Research (eg. 98, 99, 198, 199; PHYS 199H "Physics Honors Program")
There are special deadlines to apply to these courses. Please click here to learn about independent reading/research (aka Special Studies) courses and how to sign up. Start arranging and submitting your enrollment requests TODAY -- do not delay! The deadline to submit PHYS Special Studies requests is Friday of week 1; late requests are not accepted.
If you want to sign up for Special Studies under a non-PHYS faculty member, see policies here.
If you are doing well in the UD physics program, please consider the Physics Honors Program and contact PHYSICS through VAC to discuss this.
Courses Offered by Other Departments
Each department has sole control/discretion over the policies, procedures, options, limitations, and advice for enrolling in their courses (including policies/options re. course prereqs, 1st pass vs 2nd pass, waitlisting, etc.). If you have a question about a course offered by another dept., send your question to that dept. through the VAC. Submit enrollment clearance requests to other departments through the Enrollment Authorization System (EASy);
How to Use “Free” Space in Your Schedule
Consider...
- taking remaining GEs and/or university requirements;
- getting ahead in math/physics requirements;
- taking courses for a double major and/or a minor;
- taking courses that will enhance your Knowledge, Skills, and Abilities (KSAs) in your target career field;
- looking for research that could result in enrollment in a Special Studies 99, 199, or 199H course under the supervision of a faculty member;
- taking courses merely for personal interest
- Enrolling as a part-time student.

Important Information
PHYS 191 is our Faculty Research Showcase for Undergrads! Each week in this 1-unit P/NP seminar, a different UCSD Physics faculty member will invite students to take a sneak peek into the cutting-edge research they're performing. If you haven’t yet started a lot of networking with professors and/or don’t know a lot about research in PHYS, this would be a good class to take! This course does not apply to the major requirements but does count as one UD unit toward graduation.
