I registered for the SAT online and sent electronic score reports to colleges, but I would like to have a paper score report for my records. How do I get the College Board to send me one?
You can't get a paper score report sent to you if you didn't request one during your original registration.
From the College Board website: "Students who register online and wish to receive a paper score report by mail in addition to the online score report must request it when they register."
You can also receive a paper score report if you register by mail. Essentially, the only way to get one is to request it at the start of the process, so next time you sign up for the test you should plan for this ahead of time.
