You should meet with an academic counselor in your school to talk more about what classes towards your concentration you need to take. Each specific college/school has their own set of academic counselors there to help you out with anything you need. Definitely meet them to form a study plan.
Also, if your school site has a personalized Student Online Portal, explore it because it'll usually have advanced info on your required classes and stuff.
