The CollegeData mobile app provides comprehensive tools and resources that enable you to search and compare over 2,000 college profiles, see your chances of getting into those colleges, and learn how to prepare, apply, and pay for college. The mobile app also provides important college application and testing deadlines and access to thousands of scholarship awards worth over $5 billion. Use the app’s College Search tool to search and compare over 2,000 colleges by name or personal preferences including location, size, cost, acceptance rate, majors, entrance difficulty, college tuition, financial aid awards, campus life, graduation and retention rates, GPAs, test scores of recently enrolled freshmen and more. 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. Use College Chances – our college acceptance calculator – to estimate your chances of admission at any of the 2,000+ colleges profiled in the CollegeData mobile app. The College Chances calculator is a valuable and informative tool that compares data about you (including your GPA and test scores) with the qualifications of freshmen recently enrolled in the colleges you are interested in, plus other admissions factors. Using our college acceptance calculator, you can also estimate your admissions chances and find out what you can do to improve your odds using the College Chances calculator. 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.
