<p>Prospector, your question attracted my curiosity. </p>
<p>According to a Harvard Crimson survey, linked below, “Freshmen [Class of 2017] reported an average composite SAT score of 2237. The reported average subject score was consistent across the three sections, with an average of 748 in the math section, 746 on writing, and 744 on critical reading.”</p>

<p>It would be a great coincidence if the number 2237 just happened to pop up in your post and in this survey, so I guess it is what you are referring to.</p>
<p>Since the average individual section scores match up with the average composite score, I am concluding they are computed the same way…either superscore or highest single sitting score. I would guess superscore, but that is only a guess.</p>
<p>Also, according to the Harvard Common Data set for 2011-12…the latest I could find… far fewer than 75% of Harvard freshman had one individual section score of 790CR, 800M, 790W. The percentage is more like 25%. </p>
