Michigan's R1 deposit deadline this year is on 5/1, while Cornell's was on 1/31. Therefore, if you are planning on applying to one of your target/safety schools in R1, I would recommend that you do Ross first. This way, you can wait for the MIT, Northwestern or LBS (whichever of the three you do in R2) R2 decision dates before you are forced to decide on whether or not to pay for any deposits.
I didn't know that! That's great information actually thanks! I tried looking for the deposit deadline online where did you find it?
You're right. I don't think the deposit deadline was made available to the public this year. I only found out about the date after I was accepted.
FYI in case you are interested, Fuqua also has just one deposit deadline for R1 and R2 - May 1st.
