When you take a practice SAT on Khan Academy, you can now submit the optional essay to Turnitin Scoring Engine, an official auto-scoring program, and instantly get your score!  

Instant scoring is available for the essays in our first two SAT practice tests. After finishing the required exam sections, you can write the optional essay and submit it to an official auto-scoring service approved by the College Board. The score you get back will give you a sense of how you might score on a real test.

This feature is official, approved by College Board and only available for Official SAT Practice on Khan Academy.
