Hi there,
I'm currently applying to MSUCOM. After they receive a primary from you, they email you a letter saying what prereqs you have completed and what you need to attend MSU.
That letter said you need 6 semester hours of Behavioral Science. I'm not sure which of my classes exactly they counted (I was a humanities major in my previous life), but I only took 1 class of psychology. I'm guessing they used one of my various sociology/anthropology classes for the other one.
If you are on the semester system you will only need to take 2 3-credit classes (6 credits). If you are on the quarter system you may need to take 3 classes.
Email the admissions dept. (or better yet, set up an appointment with Kathy Schafer, director of admissions-- she's very helpful with pre-med counseling, not to mention very nice! ) let them know what school you go to, and what classes you were planning on taking to fulfill the requirement. They should be able to tell you if it will work.
Good Luck!
