The mobile app also provides important college application and testing deadlines and access to thousands of scholarship awards worth over $5 billion.

You can also search by financially “friendly” factors, including average financial need met, average student debt, and percentage of students getting merit aid. Next, you’ll want to generate your College List to help you find the best college match and your dream school. It’s wise to develop a list that includes reach, target, and safety schools.

If you're shocked by the cost of college, remember that scholarships and financial aid can make college more affordable. Use our Scholarship Finder to explore thousands of awards offered by private organizations, foundations, corporations, the U.S. government, individuals, and the colleges themselves. Find scholarships that might be looking for students with academic qualifications, interests, and personal characteristics like yours.
