Hi, I would take the Intro to Psychology first and the Sociology second. If the professor is an "easy A" this helps. The reasons for the "easy A" is might be that he/she is an interesting professor and is easy to understand, engaging everyone in his/her class, and so the "easy A" just comes with it (making them give better grades because they are a better professor). Psychology is useful in other classes as well, especially in English classes and even Human Anatomy during the brain section. I found Human Growth and Development to be slightly useful in Anatomy in the nervous system unit. Basic Nutrition was useful in the digestive unit. I never took Sociology myself, but took Anthropology in exchange. It's best to take a useful, "easy" class with Chemistry because Chemistry is where you will focus most of your time!! Good luck and hope you do well !
