I think you should relax. This is your first semester. You don’t suppose to take all specialized classes and you do not have to take an “official” class for every single one of your interests. What else are you planning to do? It seems to me that you can get a lot from joining clubs or organizations. Learning will occur on your other experiences/interactions as well. Also from volunteering to causes close to your heart. And again, things you learn in your history/english or other classes are not for nothing. Core classes are there for a reason. They are not fillers. Things come together to build your education. You might need those classes in order to fully benefit from the social justice class you will take later.
