Do lessons of Khan Academy’s DIGITAL SAT course use Bluebook mock test questions?

Hello, Just wanted to know - Do the questions covered in lessons (units) & tests of khan academy’s digital sat course use questions specifically from the Bluebook mock/ practice tests ? I’m asking this question for the following reason - I want to attempt the Bluebook mock tests after I’ve prepared for Sat and I want it to simulate the actual test-taking experience wherein you haven’t come across any questions before. Thank you!
