Our [public] school gave a 1-hour class on the basics of the SAT test mechanisms and how to get your score to what I'd call "reflective of your ability". If kids are showing up to the SAT barely knowing how a #2 pencil works, that's bad. If they've had 1 hour on "if you can eliminate even a single answer that you know is not correct, do not leave the question blank" and "D means that no can determine which is greater not that you have no idea which is greater", that puts them in a position to demonstrate their ability and that's well within the reach of any school district that gives half an ounce of care for their students.
