GATE

You have ample amount of time for preparation. One thing I can suggest you is to start preparation early. CS is the easiest branch in terms of GATE. The questions asked are very direct if you know the concepts. There are three options in which you can prepare. First. You can join any offline coaching institute for the preparation and they will guide you. Second. One of the best one. You can join Ravindrababu Ravula course where his strategy is mind blowing. He is a very good instructor. He charges some fees but it's almost half to that of offline.
3rd is you can do self study but for that you have to start early. Practice by solving previous year papers and NPTEL videos can help you in learning various concepts. DBMS, OS, CO, Algo are some of the major topics you should prepare for.
