I bought it from G-9 markaz rehan book shop ..... And to be honest i haven't studied much from it yet ... Just gone through few topics , and i am little disappointed , it is seriously lacking "2016" on almost every topic i have gone through e.g Kashmir ,loc situation ?? ?? although its Latest edition but not updated .... Secondly some very important topics for this year are very brief e.g honor killing , panama ... In Short ... As far as i have gone through it , This book is not enough! .. only provides base or bed or history , historical background, or just brief ideas and its very expensive too ....
