Can I print out your practice exams and automatically upload my answers to the system?
Updated
You can download/print all the SAT practice tests available in Khan Academy by accessing the article "Full-length SATs to take on paper". There, you will also find the scoring sheet for each test.
Uploading your test results to Khan Academy is no longer possible since College Board deprecated the app that allowed scanning tests to upload the score in June 2020. You can find more information about this by clicking here.
