Tution for a weak subject/s are necessary for overall knowledge improvemnt of the subject where are as coaching classes are not.Coaching classes helps to enrich the owner. Parents /children are temted to buy it when it is available in the market.It also helps to keep up egos of parents.Eg.my son/daughter is going to ------classes.Some are force to send their wards because of pressure and also in the hope of doing well in the exam scoring higher marks without knowing their wards IQ.Afterall exploitation of lesser knowledge is prevalent in all sphere of life why single out only education!
