is it hard?

Is it hard going to school and working?! I'm a college student going into my 4th semester in January. I go to community college and I'll be taking 4 classes overall in January. I wanted to know is it hard going to school & working?!? Or does it really depend? I get good grades and I'm on the honor roll by the way. So I really think I'm responsible enough to do both at the same time. I got a job at a nursing home right down the street from my school as a CNA. Which I think would be great since I'm in the nursing field. I think it'll be good to get experience. Also the job knows I only want part time so their giving me that. What do you all think?
