UC Berkeley Comp Sci in L&S

Hello everybody. I was recently admitted to UC Berkeley as an Undeclared/Pre-Business in the College of Letters and Sciences. I was going to do Computer Science as a major from the College of Letters and Sciences while trying to pursue the Undergraduate Haas Program. How difficult is the Comp Sci major from Letters and Sciences (I’m am pretty bad in physics, but decent in math and pretty good in statistics and economics). Any help will benefit me!!

L&S CS does not require physics.

Prerequisite courses for the major are listed at http://www.eecs.berkeley.edu/csugrad/#petitioning .
