Hi John,

Thanks for posting!

I've got good news: This feature actually already exists on Khan Academy, it's just a little tricky to find.

To give yourself extra time on the SAT practice, go to your Settings page. Scroll down towards the middle of the page to the "SAT extended time accommodation" section.

Here, you can adjust your settings to give you time-and-a-half or double time on the SAT practice. Don't forget to hit the save button! This will then give you extra time on the timed mini-sections and the practice tests.

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