That site is a load of poo. When I applied for college three years ago, I checked out all of these "Government Grant" sites and they're all scams, as far as I'm concerned. All that happens is that you pay them and they send you a list of grants you could find all by yourself - for free. Not to mention the fact that the grants are ridiculous and you have to be in very specific categories to qualify - Male, between the ages of 41 and 42, who rides a unicycle to work, has a baby rhino for a pet, and only eats pork fried rice all day.
Any real government grants are listed here:

Give them a look, and good luck.
