How are you covering environment for prelims? I started a standard environment book and it's huge. Would NCERTs (bio/geo bits) + a monthly CA + PYQs be enough if I stay consistent, or is skipping the standard book a bad idea?

I wouldn't skip a standard book entirely, but I also wouldn't read it linearly like a novel. I go chapter-wise only for the syllabus headings that keep repeating in PYQs (pollution, biodiversity, acts, bodies, climate). CA covers the new reports and species.

Map the PYQs first – you'll see which chapters actually get asked. That cut my reading a lot.

Will do PYQs first this weekend before touching more chapters. thanks.
