How do I deal with this kind of rejection?

As others have said getting in a top school is getting more and more random. Students apply to more and more of the top schools, and the schools admit ever lower percentages. Swarthmore was an extremely hard admit this year with a single digit acceptance rate. The school seems to have really upped its first generation, QuestBridge/other community organization, and international admits. If you didn’t have one of those hooks, the odds were even slimmer. Hang in there. By the end of the month you should have some great choices and Swat will be a distant memory. Love the schools that love you back. https://www.swarthmore.edu/news-events/980-students-admitted-to-swarthmore-class-2022
