Which Gruber's book for Math?

I don’t recommend Gruber to anyone who already knows the material. If your son has ever taken a practice test, a 650+ would definitely mean Gruber would be absolutely useless. I think it’s better towards people with a very poor starting score, but for me at least, it really didn’t help.

<p>What do you recommend to someone, who’s scoring ~700 in the SAT math? (I don’t think I have a “concept” problem.) Just a time problem, which directly leads to “low accuracy”.</p>
