Hello folks,

I am Vijay. I've been working for 5.5 years now and considering taking GMAT this April or May. I wanna apply for 2011 for bschools like ISB, NUS, AIM etc.,
Can any of you help me out with the following:

1. When do admissions procedures generally open for bschools?
2. Where can I find info regarding bschool rankings?

Thanks,
Vijay.
