<p>L&S CS does not require Physics 7A or 7B, unless you want to take EE 40 instead of EE 42.</p>
<p>L&S CS is subject to the [L&S</a> 7-course breadth requirement](<a href=“http://ls-advise.berkeley.edu/requirement/7breadth.html]L&S”>http://ls-advise.berkeley.edu/requirement/7breadth.html); one course in physical science is required, but the required CS 61C fulfills that (so could Physics 7A or 7B). Additionally, one course in biological science is required; the optional CS C182 course can fulfill that, although there are plenty of other (non-CS) choices. That’s it for L&S science requirements.</p>
<p>However, an L&S CS major has plenty of room for free electives in his/her schedule – about 15 courses for the major, about 5-6 for breadth not fulfilled by the major, 0-2 for R&C, totaling 20-23. Since you would typically take about 32 courses over 8 semesters (i.e. you would have 9-12 completely free electives), taking extra math and/or physics should not delay graduation, unless you wanted to double major with something that would not use the extra math and/or physics courses.</p>
<p>As long as you are in the College of Engineering, you might as well take physics, just in case you stay in engineering. If you do complete Physics 7A and 7B, you can choose EE 40 over 42 when you want to take that. With respect to math, you can take Math 53 and 54 in either order (e.g. you can take 54 first, then 53), as long as you take Math 53 concurrently or previously to Physics 7B (though it may be advantageous to have taken it previously versus concurrently). Physics 7A and 7B may be interesting anyway if you are good at and interested in math and science.</p>
