palash gupta

m appearing for first time in ipcc in may 13 attempt myself

anyways i will tell you wat i think is good enough for costing:

a good command over mathematics (basic maths , not derivatives , integration etc)

solid reading of theory
becos i read somewhere that costing fm is one subject where theory questions are asked explicitly

also ur practical part will be fairly easy if u have good grasp over various concepts and basic maths

i dont think der is need to solve 100s of sums for every topic


All the best
