Could you actually apply EDI to a school who offers EDI Nov 15 with a decision by mid December and then apply EDII to a different school with EDII deadline of Jan 1 if you didn’t get into your first choice by EDI? Do people actually do that if they are having a hard time deciding between 2 favorite schools and would be happy at either?
Yes you can do that … and yes a lot of people do it.
PS - If one of my kids was torn between two school I would NOT recommend EDI and EDII … I would recommend they apply to both rolling and see is a clear favorite emerges but spring. IF one of my kids had a clear #1 and then a clear #2 then the EDI/EDII strategy would make a lot of sense to me … assuming comparing financial aid offers is not vital.
