I am currently pursuing B.Tech. in Electrical Engineering from a private engineering college. I want to go for a career in research and teaching and henceforth I'm looking forward to go for M.Tech. and Ph.D., both from some I.I.T. I'm currently in 3rd year and doesn't find myself competent enough for the levels of the competitions like GATE. There is no good coaching institute for GATE in my city. Furthermore, in my college it's compulsory to do the assignments and attend the college regularly. I've one more year left with me to appear for GATE.

Can anybody please guide me how to manage both college and competitions and what to do to excel in GATE?
