First of all what is the reason for picking up GATE cse ? Is it only for the sake of placements or you want to pursue CSE ? Reason why I am asking this is – If your only concern is better placement that you will get easily with role based courses and interview prep. But if you want to pursue cse masters then gather info about syllabus and start studying. It is difficult considering 5 months duration but the end result would depend on how dedicated you are and your learning capacity. Aptitude – 15 marks, Maths – 13 marks. If you are familiar with DSA, Digital Electronics and Engg maths it would be bonus for you. You can start from these and solve PYQs. Once these are done can pick other subjects. Either you can join any coaching or go with nptel/other university lectures. Check below links to know more about resources –
