Same has been occured to me but I am trying to contact them they r not responding

Hi,

Slot booking for Amrita Vishwa Vidyapeetham has started from 12th April. If after logging in it shows invalid application number, then either you are entering wrong application number or the test centre you are selecting has been cancelled or else, all the slots are full. In either case, please send a mail before the slot booking date ends.

Hope this helps.

Cheers!
