I'm pretty sure they'll let you know via email, but you can also check your application status on their website. I think they also send you the offer on the mail.

I'm debating taking the March exam and I'm curious, are you guys going to use the March score to apply for Fall 2020 or wait until the next cycle?

Took mine 5 days ago, still waiting...

How does the study group work?

Hey there, I'm having the same doubts... but what I think I will do is apply to a few safety schools for now and wait until I get my January score to apply to my target schools. I might be wrong but I think it's better to send it all at once. Just make sure you have everything good to go as soon as you receive the Jan score so you don't waste more time completing the rest of the application then.
