It takes money to go to college. All kinds really. There's money you earn yourself. There's money you and your family can save for the future. And if all else fails, there's money you can borrow.
Some aid comes from the federal government and some from state governments.
Some comes from organizations and some from private groups or individuals who just want to help students get to college. Some aid is offered only to students who financially need it the most. Some only goes to students who excel in a sport or in academics. You might not qualify for every kind of aid, but you will almost certainly qualify for some kind of aid. Talk to your high school counselor about the possibilities for aid for your situation.
