Paper Practice SAT

Since the real SAT is on paper and not online, it would be more helpful to take the SAT Practice Test on paper. Can you make a way to upload our scores from our paper practice SAT to the website? Also, if I could upload my prompt and essay for Khan Academy to grade, that would be good as well. This will allow me to do the practice exam as similar to how the real exam will be, while also updating my customized practice on Khan Academy. Thanks!
