For anyone who has taking legal classes, is it difficult to work full time and take 9 credits a term?

I go to work 40 hrs a week but also in school. Im a little more than halfway done so I wanna start cranking out my credits. I'm taking health and domestic relations (dealing with family law) but I also want to take civil procedure. For anyone who has taking or knows anything about these classes, would it be too much to take on, or will it be okay to take all three classes? Thanks
