Environment Red book [PT Things ] for Prelims 2021

Printout nikal chuka hai! Date bhi set ho chuki hai. Jaldi hi shree ganesh hoga in notes ka! :P

I feel this book is good for veterans as it provides width assuming readers have the depth.
In my humble opinion, 1st attempters should go for Shankar and read this one as a supplement to update themselves with the latest developments.
A decent booklet nonetheless. :)
