<p>@astrophysicsmom, although the exact number is impossible to predict, the CC bunch is quite likely to have a higher percentage because they are more interested, motivated, self driven, harder working … (all the b and s). But seriously though, it is safe to say that they are mmore motivated and would have done a better job even with the same material than the overall pool. The fact that they frequent this site may also reflect that the are more serious candidates than the average. So I will dare to guess, higher than any Early Admission percentage of yale and other schools, … I will give 19.98% or 17 of 84.</p>
