Adding an extra class next semester

<p>Currently my major is CJ with a minor in Legal Administration. This week though my advisor talked to me about Human Factors Psychology and how it fits my personality more than a career in CJ does. She suggested before changing my major I take a class in it. So I'm trying to decide if I should add an extra class onto next semester. Next semester I'm taking Art, Biology, Family Violence, and Constitutional Law. These are all 4 credit hours also. Would it be too much to add another class? Do most college students stick to 4 classes? I plan on adding the class tomorrow. </p>
