We’re excited to announce that studying for the SAT for 20 hours on Khan Academy’s free Official SAT Practice is associated with an average score gain of 115 points. That’s nearly double the average score gain compared to students who don’t use our free test prep. Start studying today! http://khan.co/SATStudyonKA | Khan Academy
