This page covers unit minimums and maximums within a semester. If you are looking for information on the overall unit minimums to graduate, see the Degree Requirements page. If you are looking for information on the overall unit maximum for your time at UC Berkeley, see the Unit Ceiling and Semester Limit page.
L&S students take a wide range of unit loads, depending on what works for them. The College of Letters and Science requires you enroll in a minimum of 13 units each semester. You may enroll in a maximum of 20.5 units.
However, there may be times when it makes sense to take fewer or more units depending on your goals, time constraints, commitments, and other factors. This page will help you understand semester unit loads and how to request an exception to go above or below a limit.
If you are considering taking fewer than 13 units in a semester, it is important that you plan ahead and gain approval from the appropriate offices to avoid negative implications to your registration, financial aid, and/or visa status.
Unit Minimum and Maximum FAQs
Typical Unit Load
If a student came in with no transfer units and took no summer semesters, it would take a freshman student 15 units per semester to reach the total 120 unit minimum by the end of their 8th semester. This is why 15 units a semester is considered a typical unit load for L&S students.
That does not mean every student needs to, or should, take 15 units each semester. It is common for unit loads to change over the course of a student’s time at Cal, starting with fewer units while a student adjusts to UC Berkeley and identifies major options, then building on that if they feel comfortable doing so. Some students will feel comfortable with lower unit loads and some will feel comfortable with higher unit loads. It is important to identify an ideal unit load for you that helps you reach your academic goals.

Reduced Course Load (taking below 13 units): Am I Eligible?
You are required to take a minimum of 13 units each semester, unless you have an approved Reduced Course Load (RCL). Students with an approved RCL are still considered full-time students that pay full tuition and fees (unless approved for a rare tuition reduction. See the Registrar's information for reduced tuition).
L&S Advising can approve an RCL for students who meet one of the following criteria:
Paid employment (15 hours or more per week): Unit minimum allowed based on amount of hours worked (see form)
Eligible through Disabled Students Program (DSP): Unit minimum determined by DSP
Parenthood: Minimum of two courses totalling six units
Graduating Senior (in EGT semester only): Minimum of one course, or number of units needed to graduate
Major Honors Program: Minimum of two courses totalling six units
Approved late drop that puts a student below 13 units
If you meet one of the above criteria, see the next FAQ for the procedure to request an RCL.
If you do not meet one of the above criteria, but feel that you have a medical, personal, or family circumstances that warrant consideration of an approved RCL, you may meet with an L&S College Adviser to discuss your options and the best course of action.
If you take an unapproved RCL, you will receive a warning email if it is the first time. If you take another unapproved RCL, you will receive a hold on future registration. In this case, you will need to meet with an L&S College Adviser to remove the hold.
Reduced Course Load: Procedure
Reduced Course Loads (RCL) may be granted under certain circumstances outlined below. Petitions and other supporting documentation for an RCL must be submitted by the add/drop deadline during the fourth week of the semester to L&S College Advising, either in 206 Evans Hall or 156 Dwinelle. See the table below for specific instructions.
If you are planning to request an RCL, plan ahead and gain approval from the appropriate offices to avoid negative implications to your registration, financial aid, and/or visa status.
Students that receive financial aid should confirm with a Financial Aid Adviser whether their aid package will be impacted by a reduced course load.
Students declared in simultaneous degrees will need approval from both colleges for a reduced course load.
International students should contact Berkeley International Office to determine whether their visa status will be impacted by a reduced course load.
Student athletes should contact their Athletic Studies Center Adviser to determine whether they may enroll in a reduced course load.
|Paid Employment (minimum: depends on work hours per week, see form)||Submit completed "Employment Verification for Reduced Course Load" form|
|Disabled Students Program Recommendation (minimum: units as recommended by DSP)||Submit DSP recommendation letter or confirm that DSP has included you on their RCL list|
|Parenthood (minimum: two courses totaling six units)||Visit 206 Evans Hall or 156 Dwinelle Hall|
|Graduating Senior in EGT Semester (minimum: one course or number of units required to graduate)||Visit 206 Evans Hall or 156 Dwinelle Hall to confirm you are in your final (EGT) semester|
|Major Honors Program (minimum: two courses totaling six units)||Submit departmental verificaiton of major honors status|
Unit Max: Waitlisted Units
The unit maximum of 20.5 includes both enrolled and waitlisted units.
Students sometimes ask if their unit maximum can be raised even though they are not intending on taking over 20.5 units because their schedules are filled with waitlisted courses. Because requests to exceed the unit maximum are not considered until the third week of instruction, this strategy does not usually make sense for students. For more information on navigating waitlists, see the SIS Enrollment FAQ page.
Enrolling in more than 20.5 units
During the first two weeks of instruction, you should attend all courses you are planning to enroll in and ensure that there are no overlaps between lectures, labs, and discussion sections. If you have met those criteria, then you may request permission to enroll in more than 20.5 units (the unit maximum) during the third week of instruction. If approved, students still must add the course themselves before the add/drop deadline.
If you are undeclared: You may meet with an L&S College Adviser to request an approval for additional units beginning the third week of instruction. Note: In most cases, approvals are granted only to students with a demonstrated history of strong academic performance with high-unit course loads.
If you have declared your major: Meet with your Undergraduate Major Adviser (UMA) to request permission to enroll in more than 20.5 units.
Note: If you are declared in simultaneous degrees in two different colleges, you will need approval from both colleges to exceed the unit maximum.
