If you observe closely you can never judge what will be asked in PCS ,will it be current /static . tough or simple . But If you prepare the basic sources you may easily score 120-130 . Whatever type of Paper is there .
Just concentrate on basic , read current of at least 9month from GK Today / leadthecompitition
or follow vision’s current affair document for UPSC . or gk today membership material for current .
collecting too much material books is just a garbage collection . First finish whatever you have only then move further .
