Questions for students who reapply

Will students who are reapplying need to resend their previous test scores with their current application materials? A recent score has been sent, but a previous test is necessary in the interest of superscoring. How long does UChicago keep applicant records? Also, any feedback on the experience of applicants who were waitlisted but chose not to attend their second choice college and who have been working instead would be welcome.

Thank you!
