What should be the next step,after receiving the CAT score,regarding the admission procedures for iims and also other than iims.

After CAT score, you will get interview calls from different IIMs. Depending on the IIMs, it will be Interview and WAT/GD/Both. I would suggest you start preparing for general awareness, brush up whatever you had studied in graduation, brush up your CVs, be prepared to talk about your hobbies etc. P
