Will OSAP re-calculate the funding amount for me if I change the income information after 6 months?

Actually, I made a huge stupid mistake in the osap form when I filled it up in January 2013. I put wrong info about the "marital status" of my parents. I just came to know that if I'd put their correct status, I would get more amount of money (i.e, more grant for low income family). But I think it's too late? I mean I'm doing my 2nd semester now. I was just wondering....if I still can change that info?? and If I can do so, will they re-calculate ?? any idea?? thanks
