Dear Praveen,To improve English, delevop a habit of voraciously reading newspapers (The Hindu) and magazines (Frontline, The Economist). Refer to a good grammar book (Wren Martin) and a dictionary (Oxford), note down all the new words and their meanings. Refer to these words every now and then and try to use them in sentences so that you understand them better. See, improving English will be a long term process rather than short term course. Work on it and there would be no problem.Hostel facility is available.All the best,Rau's IAS
