Saw a special offer that might be of interest to the juniors and seniors here. U.S. News College Compass is offering a free year of their college profile search. Not sure if it's any better than some of the other resources out there, but at the cost of $0, it's not a bad option to have. Apparently Google has a special deal going on with them.
Here are the features they list on the page:
Expanded Profiles & Advanced Search for 1,600 Schools
All Entering Class Stats, Including SAT Scores & GPAs
Comprehensive Financial Aid Info, Including Average Award Packages
New "My Home" Feature: Save & Compare Schools and Take Notes
Plus: All Graduate School Data (Full Access for 1 Year from Purchase)
