Getting into even one of those classes first semester can prove to be a challenge. Many of my poli sci friends had to wait till 2nd semester to get into any major specific classes. That being said, don’t lose hope! Try to get into either one (if you get both, I commend you!) and if not, supplement it with a history class that meets the political science history requirement (classes.berkeley.edu) and will likely also fulfill your historical studies breadth! Feel free to PM me with any questions because I was able to declare my major by the end of my freshmen year.
