Majors and requirements

The Department of Physics and Astronomy offers a choice of four undergraduate majors:

• B.S. degree program in Astrophysics
• B.S. degree program in Biophysics
• B.S. degree program in Physics
• B.A. degree program in General Physics

Courses taken to fulfill any of the requirements for either major must be taken for a letter grade.

The major requirements listed below are effective beginning Fall 2022. Students who entered a physics major prior to Fall 2022 will need to follow the major requirements listed on their Degree Audit Report (DAR). For questions about which set of major requirements to follow, please check with a physics counselor.

Physics Major Requirements: Preparation for the Major in Physics (B.S. OR B.A.) required courses:

• Physics 1A or 1AH, 1B or 1BH, 1C or 1CH, 4AL, 4BL, 17, 32
• Math 31A, 31B, 32A, 32B, 33A, 33B
• Chemistry 20A
• PIC 10A or CS 30 or CS 31

(Total: 58 units)

The Major in Physics (B.S. Degree) required courses:

• Physics 105A, 105B, 110A, 110B, 112, 115A, 115B, 115C

A plan must be worked out five terms prior to graduation in conjunction with a departmental advisor and must be done in writing. (Total: 52 units).

The Major in Physics (B.A. Degree) required courses:

• Physics 105A, 105B, 110A, 110B, 112, 115A, 115B, 115C
• One course from the Physics 170 series or the 180 series

(Total: 36 units).

No course intended to satisfy the major or the preparation for the major may be taken on a pass/no pass basis and a 2.0 grade point average is required in all of the above courses for completion of the B.A. or B.S. degree.

Preparation for the Major in Astrophysics required courses:

• Physics 1A or 1AH, 1B or 1BH, 1C or 1CH, 4AL, 4BL, 17, 32
• Astronomy 81
• Math 31A, 31B, 32A, 32B, 33A, 33B
• PIC 10A or CS 30 or CS 31

(Total: 60 units).

The Major in Astrophysics (B.S. Degree) required courses:

• Physics 105A, 105B, 110A, 110B, 115A, 115B, 115C
• Astronomy 115, 117, 127, 180
• Three additional upper division electives selected from Astronomy 140, 141, 142, 143, 144, 145, 146; Physics 108, M122, 124, 126, 127, 128, 132, 180M; EPSS 155, 156, C179. At least one of the three electives must be in Astronomy.

(Total: 56 units).

No course intended to satisfy a requirement for the pre-major or major may be taken on a Pass/No Pass basis. A 2.0 average overall is required in all the above courses for completion of the degree.

Biophysics Major Requirements: Preparation for the major in Biophysics required courses:

• Physics 1A or 1AH, 1B or 1BH, 1C or 1CH, 4AL, 4BL, 17, 32
• Math 31A, 31B, 32A, 32B, 33A, 33B
• Chemistry 20A, 20B
• Life Science 7A

(Total: 64 units).

The major in Biophysics (B.S. degree):

• Physics 105A, 110A, 110B, 112, 115A, 115B, M180G, 187A* and 187B*; three additional upper division elective courses from the three groups. Students are able to choose any three courses either in one group or among the three groups*:
• Group A (Physics of Neuroscience): Neuroscience M101A; Physics 117; Physics 186.
• Group B (Biological Physics): Physics 144; Physics 117; Mechanical and Aerospace Engineering C286.
• Group C (Molecular and Cellular Biophysics): Chemistry 153A, 153L, MCDB 100 or MCDB 165A. Note that students will be advised when some of these classes have additional lower division requirements.
• *Please note that Physics 187A and 187B are only offered once every other year. E.g. 187A & 187B were offered in Winter & Spring 2022 and will not be offered again until Winter & Spring 2024. If you have any questions about when the course will next be offered, please contact a physics counselor.
• Keep in mind that some of the upper division electives may have pre-requisites outside of the Physics department. Please consult with an advisor.

(Total: 48 units).

No course intended to satisfy a requirement for the pre-major or major may be taken on a Pass/No Pass basis. A 2.0 average overall is required in all the above courses for completion of the degree.

Possible sequences of courses for the B.S. Biophysics major (4-year plan): With Physics 1A,B,C and/or the Honor sequences, there are several approaches for students considering a major in biophysics, all leading to a BS degree in four years. Displayed below are the science courses of a schedule beginning with Physics 1A in Winter, and one beginning with Physics 1A in the Fall. There are many variations possible in between. Junior transfers should see a departmental counselor immediately upon arrival at UCLA.
