Hi Esha I dont know abt krm....but as for Dpsi yes its expensive....its damn too tough...as u go in higher classes...scoring in English is next to impossible which is why kids fall off in their percentage...lot of parents have backed out,in the later stages.especially after 6 th...sp if u want to think think now....though my own kids are studying in Dpsi...1 is in 5 th and the other is studying has just started nursery.their base is excellent though...but dont know abt future
