Chance me, rising senior looking at top tier schools

@TrapNumen You have good chances for your reaches. Out of your reaches only Chicago offers EA, but since they have started having ED I/II as well, EA does not give you a significant boost there (the boost lies in their ED now).

Applying SCEA or ED to your first choice (if you have a first choice by the time you apply), might be a good strategy, it can provide a substantial boost. If you are worried about financial aid, the ED contract is not binding if you get a worse FA package than you have indicated that you needed so you are free to apply to more schools RD. As for SCEA, it is not binding to begin with.
