I’m planning to major in economics then apply to Haas my Sophomore year. Should I instead major as, “undeclared but planning on applying to Haas?” Also, how competitive are the pre-req classes?
Economics is in L&S, so if that is your alternate major, you would apply to L&S (all enter undeclared).
Note that economics is a capacity limited major that requires a 3.0 college GPA in the prerequisites.
The prerequisite courses are competitive because many are in the same situation you are, working hard and meeting the GPA to get into Haas. Keep in mind that the average GPA getting in from Berkeley to Haas is about 3.6 to 3.7, which is the GPA you would be targeting at the minimum.
