Prometric and the IIMs have released a video on Youtube about the procedure to be followed during registration. They have laid down the process very clearly and have provided information on scheduling the exam. While it does answer some questions, it does however create new doubts as well.
For example: They mention that you need to choose the colleges you are applying to – i.e IIMs/Non IIMs during the registration process.
