College Board website
"One of the great free resources that we find useful is the College Board SAT practice site. This site helps with registration, understanding the format of the test, and setting up study groups, and it includes helpful posts about test-taking. The College Board has also teamed up with Khan Academy to create some amazing practice and test review components. The app is really strengthened by its ties to the Khan Academy SAT practice site, which can also be used independently." (School Library Journal 2/17)
