Hi everyone, I'm also an M1 here. I'm a little late to the game, but I wanted to make myself available if you have any questions about the school, the application process, moving from OOS, etc. Feel free to DM or tag me.
Just some n=1 perspective: from what I can tell, most of the action happened pretty late in the cycle for us last year. I was accepted in April, as were many of my classmates (regardless of their II date). There seemed to be a lot of WL movement. This school was an add-on for me later on in the cycle, and here I am attending it <1 year later. I have a friend who applied in Dec and was accepted. If you're still thinking of applying, it might be worth it.
The cycle is inhumane and long, so if (like me), you find yourself checking SDN daily, I'd encourage you to go get some fresh air and touch some grass. Your M1 self will thank you for it.
