Want some free grant money?

I have been thinking about going back to school for some time now. I only have a semester in college under my belt, because during that semester my old job said "Hey, we're going to give you a hefty raise and let you wear jeans to work but you have to come work full time." And I said okay. And then a year later the stupid store closed and I was left hanging in the air not knowing what the hell to do.
So I have been thinking about what I want to do, except I don't have any money. My mother works for the state college here, and they can give me some assistance, but that assistance doesn't cover books and lab classes and many extras, and I don't see myself using my rent money for that.
So my mother tells me about this web site she has heard some students use: http://www.FreeGrantSearch.com'>Freegrantsearch.com. From what I saw when I looked at the site, they provide you with free grant money that you won't have to pay back. I didn't think she was serious, but I looked around and saw some grants that they offer, like $20,000 for a down payment on a house for first time buyers. Who doesn't want to own their own house? And not have to wait ten years to save the $20K? They offer money that you can use for anything, whether it be renovating your house, starting a business or going back to school. So my homework assignment is to go on a mission to find out how much I can get so that I can go back to school so when Little Man comes to ask me for help with his homework I don't have to sit there with a blank look on my face. I mean, I like giving my Famous Blank Stare, but only when people ask me stupid questions...
