Finding a SAT Math Tutor

The first time around Greg self-studied, using the 'Ziggy method' . Obviously that didn't work as well for Math as for the other two tests. So this time around we've decided to hire a private tutor who focuses on SAT Math. The thinking was that this would be the most focused, time-efficient way to improve. In fact, the tutor we choose guarantees a 50 point/section improvement and averages an 85 point/section improvement. So if Greg is just average (and diligently does the homework they assign), he should hit is goal of approaching 750. The other data point that gives us some confidence is that he recently scored a 780 on the Math2 SAT Subject test.
In my next post I'll describe the process we used to find and select the tutor, and who we selected. Then as the experience unfolds I'll post from time to time on how it's working out.
