The discussion centers on finding data regarding the undergraduate institutions of students admitted to Ivy League graduate programs, particularly in mathematics. Users express interest in compiled information from third-party sources, but it is noted that individual graduate program websites often list the CVs of admitted students, which can provide insights into their backgrounds. Dartmouth is mentioned as having data on transfer applicants, and there are suggestions to meticulously record data on incoming students and their previous institutions. The conversation highlights that while prestigious schools like MIT or Ivy League institutions may offer more resources, the quality of one's work and research opportunities are ultimately more critical than the name of the undergraduate institution. Concerns about selection bias in graduate admissions are discussed, emphasizing that strong applications can come from less well-known colleges, especially if candidates engage in research opportunities. Overall, the consensus is that while institutional prestige can play a role, individual effort and accomplishments are paramount in the admissions process.
