When is the best time to apply for a grant at the beginning or end of the year or when?

Answer 1

If you're talking about a grant toward college expenses,, file as early as possible.

If you're talking about a grant to pay off your bills, start a business or buy a house, or some other personal thing, forget it, the places that tell you they'll help you find one (after of course you pay their fee) are scams.
