@ivyyhopes There are no numbers for SCEA, but here are the statistics for the RD Class of 2019:
Total Applicants: 27,290
Total Admits: 1,948
Total Enrolled: 1,322
Total Acceptance Rate: 7.14%
Total Yield: 67.86%
Total AB Applicants: 19,903
Total AB Admits: 1,449
Total AB Enrolled: 1,009
AB Acceptance Rate: 7.28%
AB Yield: 69.63%
Total BSE Applicants: 7,387
Total BSE Admits: 499
Total BSE Enrolled: 313
BSE Acceptance Rate: 6.76%
BSE Yield: 62.73%
Total Percentage of AB Applicants in Pool: 72.93%
Total Percentage of BSE Applicants in Pool: 27.07%
The SCEA applicants are also factored in this data. This was for the entire Class of 2019 application season, however, so I do not know if this information can be generalized to this year’s SCEA numbers. Princeton does not release its AB/BSE numbers for SCEA, so this is probably a rough estimate (the SCEA pool, however, is a sample of the entire applicant population, so the 73/27 split between AB and BSE is probably close to the actual percentages).

There is, however, a good way to formulate the numbers for the SCEA round from this CC community. I know that it is statistically flawed to use this thread as a sample, since it wouldn’t be random (convenience sampling is a really bad technique that can result in serious errors). However, since the choice between AB and BSE is pretty much independent of whether or not a person is on CC, I think that a close estimate can be achieved by conducting a brief survey. Here are the basic instructions:
Click LIKE if you applied for an AB degree.
Click HELPFUL if you applied for a BSE degree.
The day before decisions, I’ll come back to this post and make an estimate to your question. I don’t know what’ll end up happening, but this is worth a shot. Hopefully this helps!
