<p>It does seem that 1500 is a bit too high. Often times one person may be good at one section and bad at another… Considering that the ACT only had about 100 people get a 34 or higher it is reasonable to have less 2250+ sat scores than the 1500 you predicted. The number may be closer to 300 if you think that the 1% who got a 750 in at least one section didn’t do so well and only about a fifth of them were 750+ material on all 3 sections. Lets say there were 1500 ‘750+’ scores for each section on the SAT, we could view it as different people got a 750 on math than the people who got a 750 on critical reading. Overall assuming 1500 people got 2250 means that people either got 750+ on all their sections and the rest did not reach 750 in any section. Therefore there would be much less 2250+ scores than what was predicted.</p>
