Do free grants help students?

When I started going back to school in the fall of 2007. I had no money so I applyed for a free grant to go to school. With grants you have to be enrolled in so many units and keep your gpa up to keep your grant. If you failed to follow these guidelines not only do you lose grant money but you have to pay it back. Personaly I believe that grants are better because they make you more accountable for your education. You don’t take it for granted like you would if someone like a family member was paying for it with there cash.
