Special nerd note: #20 in Section 4 is pretty much my favorite Guesstimate question of all time. 
The College Board’s latest The Official SAT Study Guide with DVD is exactly the same as the 2nd edition, except that it comes with a DVD containing a bit of extra content. I can see the utility in the SAT timer it includes, but otherwise the only content of value on the DVD is one additional test—the January 2008 QAS. I went through that test yesterday so I could update the Blue Book Breakdown in my Math Guide (I’m calling it Test 11). A PDF of that page (with page number references, etc.) is available here for book owners. For everyone else, below is an HTML version of that table with links to some important strategies.

Draw it. (5, 0) is on the circle, so the distance to (13, 0) is 8.
