First post so sorry if formatting gets super messed up. I am an undergrad at UW but am really close to multiple people on different admission committees as well as helping out the graduate coordinators. It is a rolling admission and it depends on which program you are applying to. My PI and another professor I am close with are on the admissions committee for inorganic and still have many more applications to sort through. Materials is also not super far along. That being said analytical, organic, and physical are fairly far along or have decided already. I would say don't be nervous but considering my anticipation to hear from the schools I haven't yet (especially given my rejection from northwestern today) I know this advice would not be listened to =). Hope this information helps.
