Dear Mr. Mishra,
I really do not have a good knowledge about this. All I know is there is Pusa Institute which has summer courses or short courses (you will have to find their address and ask them--it is near Karol Bagh/Patel Nagar). There is a polytechnic in south Delhi, called South Delhi Polytechnic. Besides these there are a lot of classes advertised.
