<p>Yes, there is a CS major in L&S.
[Degree</a> Programs | EECS at UC Berkeley](<a href=“Academics | EECS at UC Berkeley”>Academics | EECS at UC Berkeley)</p>
<p>L&S CS requires 15 courses.
Economics with less math requires 12 courses.
Economics with more math requires 14 courses, plus additional math is desirable if going to graduate school in economics.</p>
<p>However, the majors overlap in Math 1A and 1B, and Math 54 if you are doing economics with more math. Additionally, one of Economics 101A, 101B, or 141 taken for the more math economics option can be used as an [upper</a> division technical elective for L&S CS](<a href=“http://www.eecs.berkeley.edu/csugrad/tech_electives.shtml]upper”>CS Major Upper Division Degree Requirements | EECS at UC Berkeley). So that means 2 to 4 overlapping courses, which means a total of 25 courses needed to complete both majors. And if you have AP credit for Math 1A and/or Math 1B, then you can further reduce the number of courses. A 4 or 5 on both AP economics exams fulfills Economics 1 as well.</p>
<p>That still leaves space in your schedule to take the 4 to 5 courses you will need for the [L&S</a> 7-course breadth](<a href=“http://ls-advise.berkeley.edu/requirement/7breadth.html]L&S”>http://ls-advise.berkeley.edu/requirement/7breadth.html), and up to 2 courses for [url=<a href=“http://ls-advise.berkeley.edu/requirement/rc.html]L&S”>Reading & Composition | L&S Advising]L&S</a> reading and composition<a href=“which%20may%20be%20fulfilled%20by%20AP%20English%20credit%20with%20high%20enough%20scores”>/url</a>, assuming you take about 32 courses in 8 semesters.</p>
