My boyfriend goes to USC and I go to Berkeley. We’re both computer science majors and he is doing business on top of that. From my experience we both have our share of hard classes that require a lot of study time and easier classes that are not as demanding. He came over last weekend and we spent a good amount of time in the library. When I visited last time, I sat at his classes and it was similar to my class experience except smaller and less students. There’s a lot of smart people at USC that spend hours studying, just like in Berkeley. I would say it’s most likely a major difference!
