As an SAT math tutor, I specialize in helping students review content and identify strategies and shortcuts that will allow them to solve problems methodically. I have worked with several students on comprehensive SAT math. I am especially well-versed in teaching the geometry and probability problems. In my view, the most important strategy to use on the SAT math sections is to maximize the number of questions answered correctly. To that end, I think the best test strategy is to not rush but to identify the problems that can be solved most easily. After the "easy" problems are done, I encourage my students to tackle more time-consuming problems, with the caveat that an educated or "estimated" guess is better than no answer at all.
