<p>A word on the Kaplan SAT II books though. I believe the general concensus is that they are generally tougher than the actual tests (at least the Math IIC was), so don't get discouraged if some number of the problems in them are outside of what your son has been exposed to. The grading curve is fairly generous on the IIC, as well, so 5-6 wrong can still give an 800 (I think that's right, but it's been a couple of years).</p>
