<p>sure, put the 91. It isn't going to make them sit up and get excited, but it is a good, solid score. It certainly won't hurt you, if that's your concern. And like other standardized test scores, it will give them a benchmark to compare your app to others. Sometimes the same course title and grade can mean very different things at different high schools, and scores on nation-wide tests help to sort that out. The AMC exams may not seem to correlate to SAT scores, because they test at a much higher level and are intended to spread out the top people. The SAT isn't really designed for that purpose. I have never seen any kind of comparison of scores on the 2 exams, but I would guess that most people who score 90+ on the AMC 12 would probably also score 700+ on the math part of the SAT. There are probably people with your AMC score who had 800 math scores (maybe even you). That wouldn't really be inconsistant.</p>
