I just got the first (maybe only - who knows) email from an admissions department reminding about March 10. As if we could forget! 
As for a March 10th plan, we don’t have one in place. It’s a little easier here as only one decision will come out before school on Friday morning. The rest will come out in the evening or even on Saturday due to where we are in the world. So, hopefully the one that comes out before school is good news. All she needs is one, so that would make her happy!
