Has Ohio State responded to anyone here yet?
It probably wouldn't hurt to ask the programs if you can still send your grades in. A lot of those places will have started to send acceptances by mid-February but they also waitlist and send out second round offers later. Have you tried asking your school if you can get your grades early?
Does anyone know about the Michigan State interviews? Looking back on gradcafe it doesn't look like they have ever had interviews before.
Also I can confirm that Ohio State has sent out a few acceptances. I know for the Ag Econ program they have accepted around 10 people, which is not their full class.
