The William Lowell Putnam Mathematical Competition is the preeminent undergraduate mathematics competition in the United States and Canada. Each year on the first Saturday in December, more than 4,000 students spend two 3-hour sessions solving 12 problems. Prizes are awarded to the participants with the highest scores and to the mathematics departments of the five institutions whose teams obtain the highest rankings. Over the years, many of the winners of the Putnam competition have become distinguished mathematicians. A number of them have received the Fields Medal, and several have won the Nobel Prize in Physics.

In 2022, MIT mopped the floor with the Ivy League schools. And this is because MIT admissions policy
1. Requires SAT
2. Doesn't discriminate against Asians
3. Doesn’t use legacy

Herewith, the results of their policy. https://www.maa.org/sites/default/files/pdf/Putnam/2022/AnnouncementOfWinnersFall2022.docx%20%281%29.pdf
