<p>Hm,</p>
<p>My son took the SAT in 7th grade after watching some math SAT videos. His scores were 700M, 610 CR, and 540W for a total of 1850.</p>
<p>He took it again in 8th grade without studying and got an 800M, 640CR, and 680W, or a 2120.</p>
<p>He took it one last time as a junior without studying (at least I can’t recall that he did; I do specifically remember borrowing those math videos from a friend when he was in 7th grade) and got 800M, 790CR, and 730 W (down from a 78 on the PSAT), for a 2320.</p>
<p>Not sure what the SD is on that.</p>
<p>Edited: I think my son did some studying for CR at some point, but I don’t remember what it consisted of.</p>
