what are the chances of converting any new or baby IIMS?
I have converted great lakes PGPM chennai. The last date to withdraw from it is 1st may 2022 but IIMs results will come after that. What should I do? Should I go for great lakes or should I withdraw from it and wait for IIMs results?

What did you do? did you join great lakes or got a IIM?
