Make sure everything is neatly typed and letter perfect. Beat the deadline by a few, days if you can. Then sit back and wait. Financing graduate school is different from financing college. You have to look up their financial aid provisions and policies one by one and apply accordingly.
Graduate schools keep their own lists of financial aid resources.
For example, if your mother is a member of the Daughters of the American Revolution, there are fellowships. And so forth. You can find these special fellowships listed in directories in the library and the Counseling and Career Planning Office. Assistantships are jobs teaching, counseling, and grading work of undergraduates. Many assistantships carry tuition waivers or honorary in-state tuition rates that can be worth many thousands of dollars over and above the pay rate, which is usually OK but not great.
