I got waitlisted without interview at Cornell round 2 mba application. The adcom suggested me to write gmat again. I was wondering how much time I have to write my gmat again in order to have sufficient time for interview and get admission this year itself. Although the adcom mentioned that people remain on waitlist throughout the summer also but wanted to hear from experts here. I am an international candidate but don't mind deferring the admission if I don't get visa this year after admission
