I condensed the whole BC into 10-15 odd pages of spectrum that made revision easy

About eco book: In my personal view, I didn’t find any book more worthless than Ramesh Singh’s. Sorry Mrunal, but here I sincerely deviate from your recommendation of Ramesh Singh.
|Science (theory + current)||GS Manual (only Physics) + NCERTs 6-11th|
|Environment (theory + current)||Did gadha majdoori in this topic, internet digging, so can’t recall from act source + Shankar IAS Printed notes (just for the sake of competitive edge)|
|geography world||GC Leong|
