Students now have access to free SAT coaching through a partnership between the Khan Academy and the College Board. The College Board recently reported that students who used the program gained on average 55 points over students who did not use the program. There are no rigorous, recent studies of test gains made by students who took a for-a-fee test prep courses outside the College Board program, but this free option may be a good alternative for those who do not want to pay for prep courses.
