SAT: Khan Academy Improves Your Score
On May 8, 2017, the College Board and Khan Academy announced promising new findings, based on data from the first full year of the new SAT®.
Studying for the SAT on Official SAT Practice for 20 hours is associated with an average score gain of 115 points. That’s nearly double the average score gain achieved by students who don’t use Khan Academy.
Out of the nearly 250,000 test takers studied, more than 16,000 gained 200 points or more between the PSAT/NMSQT® and SAT.
In addition to the 115-point average score increase associated with 20 hours of practice, shorter practice periods also correlate with meaningful score gains. For example, 6–8 hours of practice on Official SAT Practice is associated with an average 90-point increase.
