for more information.*

## Lower Division

The Physics 1 sequence is primarily intended for biology.

The Physics 2 sequence is intended for physical science and engineering majors and those biological science majors with strong mathematical aptitude.

The Physics 4 sequence is intended for all physics majors and for students with an interest in physics. This five-quarter sequence covers the same topics as the Physics 2 sequence, but it covers these topics more slowly and in more depth. The Physics 4 sequence provides a solid foundation for the upper-division courses required for the physics major.

**Note: **Since some of the material is duplicated in the Physics 1, 2 and 4 sequences, credit cannot be obtained for both (Example: Physics 2A followed by Physics 4A, no credit for Physics 4A.) Please review the individual course descriptions for complete information on credit limitations.

Physics 5, 7, 8, 9, 10, 11, 12, and 13 are intended for nonscience majors. Physics 5, 7, 8, 9, 10, 12, and 13 do not use calculus while Physics 11 uses some calculus.
