Hey bb, Happy to share what ended up working for me. Here was the structure I used for my Tuck WL essay, which got me off the WL much quicker than Kellogg.
I approached the essay by aiming to prove that Tuck was my number one choice and that I would be a contributor to the community. I mentioned specific conversations I had with Tuckies (naming them), I mentioned how I attended one of Tuck’s tech conferences, I also briefly explained how my work experience would bring a unique perspective to the classroom. I also wrote which organizations I would plan to contribute to (naming Tuckies who I had spoken with and were leaders of the clubs). Lastly, I explicitly said that Tuck was my number one choice and I enthusiastically accepted a spot on the waitlist.
Hope this helps! If you got Denied/Waitlisted in Round 1, there is always Round 2!
