Unfortunately, you cannot connect your Khan Academy and College Board accounts to import your past Digital SAT scores. This feature was only available for the traditional pencil-and-paper SAT and was removed on December 31st, 2023.

For the Digital SAT, Khan Academy provides articles, videos, and practice questions.

I recommend continuing your preparation using Khan Academy's Official Digital SAT Prep for skill building and College Board's Bluebook app for full-length practice tests!

Hope this helps!
