The many young ladies who received appointments obviously earned that honor. I suspect some of those ladies may actually have had higher grades and scores, others may not. Since the appointments are based on a large set of criteria - grades/scores being about 60% - we never have the full picture. Only the admissions people do. They have a tough, tough job. And quite frankly, they are very good at it.
At the risk of repeating myself, those that are still in the game in March and beyond are all qualified, hard-working, deserving young people. There are only a small number of appointments and too many very qualified applicants. Even tougher for those who are in a highly competitive area. I truly hope that those who received TWEs this late in the game will reapply next year - but for now, embrace your plan B. You may find that it really is your Plan A.
By the way -- all those awards and accolades you've earned to get this appointment? Yah, means nothing to those mids that will train you. You're just an average Joe in a class with equally talented and brilliant plebes. You suddenly find out that you're not that special. A tough lesson to learn, but my DD did & is better for it.
