So far I've been working on/submitting secondaries roughly in the order that I received them with the goal of returning all secondaries within 2 weeks of receiving them. However, some schools have started extending Interview Invites already (UVA, Chicago) even though I got their secondaries within the past few days. Would it be wise to shift my focus to these schools and get them in ASAP given that they're already handing out spots for interviews?
