Scholarships are available from many resources and can be awarded based on merit, need, talent or service, among other traits.
Generally non-repayable funds, you'll want to research all scholarship sources each year to see if you qualify. In some cases, awards might be renewable. If they are, make sure you meet the requirements each year.
Please note that you are required to notify the Office of Student Financial Aid of any external scholarships you receive. Such awards are counted as a resource and will reduce your eligibility for other need-based aid.
