Kerala public service commission previously published the special edition book in the silver jubilee. The edited book contains more than 12,000 general knowledge questions and answers. It also includes confusing facts and some related things. The digital edition currently not available in the market, so the KPSC officially published the Ebook edition. We edited this PDF file and only add useful information like general knowledge questions and answers. Other unwanted data removed for easy to read and study. Now the Kerala PSC released diamond jubilee 2nd edition book at the price of 250 rupees. Diamond edition PDF (ebook) will be updated on this page as soon as possible.
