Best teacher for costing in india

both are good, but sanjay gupta sir i recomend

sanjay agarwal

Both are good teachers, but as per some of my friends, Sanjay sir is not covering several topics like  Theory of constrainst, Minimization problem by Simplex method, etc

Although questions from topic like theory of constrainst is very much frequent.

Also he teaches wrong basic concepts of relevant costing (Source : /forum/sunk-costs-are-irrelevant-but-irrelevant-costs-are-not-sunk-79001.asp)
