Medical Assistant or Nursing

Hi, I'm in a little bit of a rut. I would like to go into nursing and get my LPN. But I went and talked to a counselor if I should do this or not. She recommended with my grades (not being great) that I should try and get into medical assisting instead and come back to nursing later on. Are grades REALLY that important in nursing? I mean I know for a fact I could never make straight A's, maybe B's. My GPA is a 3.0 right now. But I'm just wondering if I have all my pre-reqs done, apply to nursing school at several different schools, that one of them would let me in. But if I go into medical assisting instead, money isn't that great and it'll be easier to get through. What do you think I should do? Is medical assisting the alternative for people with not so great grades? Thanks.
