Social Studies classes

What classes did y’all take for social studies ? I’m not American but I want to study there and I’m starting an American-based online course for this school year.

I’m wondering which classes to choose, so far I’ve got : one year US history, one year world history, one semester US government, one semester economics.

Which would be 3 credits, to make it to 4 would it be best to take one semester of philosophy &ethics and one semester of sociology or one year of psychology?
