How difficult is it to get into U.C. Berkeley’s Political Science Undergraduate Major ?
Political science is in the College of Letters and Science (L&S), which is the largest division at UCB. L&S admits all frosh as undeclared, so there is no difference in selectivity by intended major. Some L&S majors are at enrollment capacity and require college GPAs significantly higher than 2.0 to declare. However, this is not the case for political science, since the only requirements to declare the major are passing specified prerequisites with a 2.0 GPA overall and in major courses: http://polisci.berkeley.edu/undergraduate-program/declaring-major .
So if you can get into UCB L&S (which is not easy), you can get into the political science major as long as you can pass the specified prerequisite courses.
