So what? The EA applications will be done and submitted. If you get deferred, you will be considered in the regular decision round. And you might get accepted someplace EA.
If you are working on college applications now (which you would need to be doing for ED or EA, just submit them. It will make the rest of your last year in high school much nicer…you won’t be staring at completing more college applications.
Disclaimer…both of our kids had all of the applications except one submitted by October 15. They were glad they did.
