Shorter periods of practice also correlate with meaningful score gains. Students who practiced 20 hours on Official SAT Practice achieved an average 115-point score gain on the SAT – nearly double the average gain among students who didn't use Khan Academy.
The extensive analysis included nearly 250,000 students from the graduating class of 2017 who took the PSAT/NMSQT and the SAT in the past year. The College Board and Khan Academy have released data linking Official SAT Practice on Khan Academy to substantial score gains from the PSAT/NMSQT ® to the SAT.
Though this can be a stressful point for many students, the good news is that SAT practice can significantly raise a score. Most colleges use standardized test scores as a key component in the college applications process.
