I would suggest you to understand the basic issues like Kashmir, War on terror, Neocolonialism, poverty, blah blah first from authentic books etc and then go on studying all this material. Make it habit to comment on them with your own opinion.
I think it will be better not to copy or make notes of columns etc. Only try to remember facts and figures, if authentic, from these columns.
I have seen your threads on current affairs. You are really doing well. If you continue these efforts, you will be among the toppers. cheers!
