Most holistic is a myth. Most often, at least in the initial days, we will have so many doubts - Will everything come from this magazine? Will I miss out something? Can I be able to write answers well for GS-2,3 by relying on this magazine? Which has the best coverage?
Here is my 2 cents experience. The idea of the holistic magazine is a myth. None can cover everything. Pick up any leading institute's magazine. Anyone of your choice, be it Vajiram, Vision, Forum, insights, IASBABA , NextIAS, Shankar. Pick anyone and follow it religiously. Make separate notes especially for mains. Follow the rule of 25% i.e.; whatever be the length of the article, for mains you need to tone down it to 25%. Revise it multiple times. Make questions on the contents, try to write answers. For prelims do solve a test series and a quiz booklet of any leading institute of your choice. Before the prelims, revise the quiz booklets and factual stuff from the magazine -preferably underline it with a different colour while reading.
That's it! Don't lose yourself in the sea of magazines and short notes mafia. Trust me, I've seen the worst and on my way to best.
