Grants and scholarships are the same - money given to you so that you can attend the school because they want you to attend. Typically, these schools include in their costs the fact you’ll need to buy a coat and heavy winter boots, transportation, books, etc, so there’s a way to cut down on remaining costs (for instance, buy used books and not new; plan your plane tickets in August for Christmas, or even consider if sharing a ride or finding a bus is feasible. Don’t skimp on the coat and boots though :p).
You need to ask about outside scholarships. Some of these schools may not offer you loans, so that you’re free to take on loans for that portion, if need be (but typically you can cut those costs in two if you live frugally and don’t buy new books etc.)
