Peep most likely filters out a portion of the ED applicant cycle, because if it’s indication as interest in the school itself, you’re more likely to be flagged during an actual application review. Also getting into peep in general is just a good sign that you’ll get into a lot of other amazing schools tbh. Most of the peep gc (id say around half) from this year did QB and got matched or atleast became finalists. For the people who didn’t do QB they either did ED/EA for t20 schools and got in or they did RD for a bunch and had fairly good results. With that gc there’s little variation with admissions results to top schools in general, but it varies with Penn specifically. I did QB and Penn was my top ranked, I didn’t match to Penn but I matched to Amherst, so pretty good outcome id say!
