Hi tdouellett22,

You can learn more about SAT time accommodations here: https://accommodations.collegeboard.org/request-accommodations/overview

As the College Board article takes, the approval process can take up to 7 weeks, so it is best to start right away.

To receive extra time on Khan Academy's SAT Practice, he can change his time accommodation settings in his Account Settings.

Hope this helps! Please let me know if you have any additional questions!
