cs70 is required for L&S CS majors; EECS majors have a choice of cs70 or Math55. Broadly speaking the two courses cover similar material; however, Math55 covers a wider range of topics in less depth and with fewer applications, and is less closely tailored to Computer Science. You should take this course as an alternative to Math55 if you are intending to major in Computer Science and if you found the more conceptual parts of CS61A enjoyable and relatively straightforward.
The following schedule is tentative and subject to change. Readings in Rosen are optional, in case you want extra background on the subject or a different presentation from a second point of view.
