Hi Mike, I scored a 660 on the math section on the SAT. I did not answer the last two or three math questions from each section so I wouldn’t risk getting them wrong and so I would have more time for the easy/medium questions. My main question is how do I deal with the hardest math questions on the SAT? Are there certain strategies that work better for the harder questions (i.e. backsolving tends to work better on the harder questions)? I do own a copy of your Math Guide, by the way.
