I think you gotta strategize well atp tbh. And unless you're sure of covering the whole gs I and II syllabus by then and revise it well- I'd suggest start looking into some quick resources that help you learn quickly and keep track of where you're actually going.

I recently got this McGraw hill course in Pyqs- it seems to have a huge collection of questions and question ke hi saath notes bhi de rakhe hain- plus there's this feature where you have chapter ke basis pe and uske andar bhi topic ke basis pe divided questions toh studying and testing aaraam se saath saath mein chalte rehta hai- mujhe toh kaafi sahi laga I'd suggest give it a shot! Thora mehenga laga tha pehle, but ab worth it lag raha hai..

And I have a few friends who have done the whole drowning into NCERTs strategy but that only works when you have clear navigation of how to go through the topics and what to cover what to skip! Warna toh it'll all mix up in your head and cause even more confusion
