Hi, 

I am sorry but with this score its difficult for you to get a seat in IMS.

Especially keeping the fact of high cutoffs in mind.

Last year the closing score was around 380-400.

However you can try for other deemed universities especially those with a little high fee structure. Because their cutoffs tend to go low. 

I shall give below the link which can be handy:

All the best.
