Thank you for your kind words!
I was planning on applying to JHU using their ED2 application. I had no plan on applying to Stanford using REA, Rice is my first option.
Depending on what schools I get into during the EA round (Rice, Tulane or USC) I will remove some of the T20 colleges from the RD round. For example, if I get into USC I will most likely remove Pitzer or Cornell from my RD list.
Overall, I don’t think there are too many supplemental essays to write. I’ve already written around 50% of the essays for the colleges I’m applying to early, and most of the colleges I’m applying to have only 1-2 essays
