Did Northwestern really have a 5.5% acceptance rate this year?

I’m super stoked that I got in for engineering, but was the acceptance rate really that low? I had some average stats. i had Cs on my transcript in various classes, including a math class. I’m not a URM btw, so I’m just wondering lol.

If they actually have a 100% yield in RD, it will be 5.5%. But we know that it is not the case. They accepted a bit over 1000 in ED, and probably close to 3000 for the remaining 1000 slots, which might put their acceptance rate at 11%, and RD acceptance rate probably around 9%.
