Does anyone know about the changes in their admissions being earlier this year? Especially with that email they sent us

Also,

Can someone explain how this waitlist and acceptance stuff work? Cuz it seems like they are going to 200-210 seats, but around 90 are taken with early assurance/decision. But last year, 895 people were interviewed according to AMCAS. And their AMCAS listing says they have 800 waitlist spots and 300 get taken off. Does everyone get put on the waitlist first, then? Or is AMCAS wrong about either the total interview number or waitlist number? Seems concerning ngl
