Hi I will be a freshman at Berkeley in the upcoming Fall. I took AP microeconomics in high school and did very well in the class. I figured I will know as much econ now as I do ever, so i Phase 1'ed Econ 1. However, many people strongly advised against this. Is econ 1 with Olney really that difficult that I should not take it first semester? Thanks. Should I get acclimated to Berkeley first?
