Switching majors after transfer? UCLA

I am on pace to complete every pre-requisite for History major, but I changed my mind in the major I would want to pursue as Linguistics & Computer Science. At my community college, I have completed Calculus I and II, but haven’t completed a single language course, although I might in the Spring and Summer if that will help in switching the major. What are my chances of switching from History to Ling/CompSci?
