Does anyone have a good source for applicant data?

I like NCES College Navigator for high-level application stats and comparing colleges using the same metrics. The individual school's Common Data Set stats also provide a little more detail on those stats. However the most reliable data on CDS and other sources seems to be more focused on enrolled student data.

I'm curious if anyone can suggest a source for data on the applicants themselves, like distribution of GPA and Test Scores? For instance, how many of Harvard's 57,000 applicants had at least a 4.2 GPA and 1500 SAT? Or alternatively, how many of those applicants were just throwing hail marys with less than 3.75 GPA and under 1400 SAT?

Somewhat related - I'm also curious if anyone can confirm how to verify if GPA reported on the CDS section C11 are the Weighted or Unweighted grades?
