Tip 3 : Also whenever you're not able to solve the problem, check out the editorial and then re-attempt it again. Also, check the discussion if there is some good solution to the same problem.
Tip 4 : For OOPS, DS and programming, I recommend Codezen, Leetcode, InterviewBit and GeeksforGeeks.
Tip 5 : For OS, DBMS and Computer Network, I recommend GateSmasher, Knowledge Gate and TutorialsPoint.
