Oh, heck yeah. I’m stoked you wrote your post! Welcome to CC!
Just to reiterate what others have written, I think ED — as a general rule — should be used for the school that you absolutely want to go to, forsaking all others. Using ED as a way to get into a school that you aren’t as interested in but that has a smaller number next to it in USNWR is, I think, a trap. I understand the tension, though!
Setting prestige aside for a second, are there any other schools that have felt like an even better fit for you than W&M? Any schools where you’ve connected with professors the way you have at W&M?
If you want to hold on to options, you have an excellent record, and I would be rather surprised if you didn’t get in to W&M during the RD round. So I would think that if there are other schools that have spoken to you where you want to shoot your shot with an REA or SCEA application, you could then submit your W&M application in the regular cycle and it would go well for you. And you wouldn’t have a nagging question of “agh, maybe I should have played this differently.” The downside: significantly more stress! Fuss and bother and more applications! (Note: With as much as W&M has resonated with you, I would not close the door to it by ED-ing anywhere else.)
As @thumper1 and @Collegequestions5 pointed out, how great would it be to send in your application to W&M and be done early? To echo them, W&M feels like a really great fit for you. And, as @Bill_Marsh said, you’re not selling yourself short. It’s an amazing place. Per my post from a few months back that @tamagotchi cited, in my opinion W&M is the ne plus ultra of admit rate arbitrage. The ultimate “work hard / play nice” school. Warm academia, through and through. You’ll absolutely love it if you go.
However your journey goes, please don’t hesitate to post more here with your thoughts / questions. Folks here would love to help you out.
