Hi there! I applied to all of the same programs (organic) besides Rice. From following the results page, I think Caltech has finished their admissions process. I already heard back from Yale, Columbia, and UW-Madison. In the results section, a current Yale student said that the department will be sending a few more acceptances. I also saw on reddit that Columbia might be sending out a few more acceptances. I have no information on where UW-Madison is in their admissions process. I think Stanford has started to send some informal acceptances (based on the results page). No word from MIT.
