<p>Sorry to start a new thread, but it seems like a separate topic. There are several books with hard SAT math problems, most at least as hard as the hardest problems on the test.</p>
<p>I couldn’t find anything with hard writing questions. They would be particularly useful for tutoring, since the writing questions are not grouped by difficulty on the real test as the math problems are. I would also find them useful practice, as I can score close to perfect on both sections.</p>
