For heaven's sake please do not ask this person called Sivaraman to teach in a village or his neighbors. His write up is sufficient to kill the enthusiasm of even those few brilliant students in a village. This fellow could not even make use of the spell & grammar check in the computer before posting his message. Do you expect him or people like him to do any good to the society? Leave it to brilliant people like Gopinathan about whose caste we could not care!
