The College Board and Khan Academy unveiled a new set of tools Tuesday designed to make it easier for kids to study for the new SAT. The resources include four full-length practice tests, thousands of practice questions, interactive video lessons and study tips. According to a press release from the two companies, the tools are supposed to level the playing field for students who cannot afford luxuries like private tutors and test preparation classes for the influential college entrance exam. In March 2014, Khan Academy, a company that provides free online education content, and College Board, the group that designs the SAT college admission exam, teamed up for a "historic" partnership that would make test-prep materials available for free.
