I went to IIT Bombay for M.Tech. in Computer Science.
My advise to young aspirants is that they should learn to value time, have a schedule of study which they should abide by, when studying try and appreciate the knowledge in the books, ask the question why and what next, and enjoy the studies. Its not called hard work, its called appreciation of the engineering knowledge, the desire to know it all, and put it to use. Desire to innovate is the next step.
