If I am admitted to YSPA, does that bolster my chances for admission to Yale College as an undergraduate?

There is no connection between admission to YSPA and undergraduate admissions at Yale. That said, many YSPA alumni have been admitted to and matriculated at Yale. A summer on campus is a great opportunity to see if Yale is a good fit for you, and glowing letters of recommendation from YSPA faculty can’t hurt your chances for admission to Yale or any other college!
