i read all friends suggestions about reading the kinds of books. i think farha khan is right. dogars all three kinds also provide enough knowledge for passing css it makes no difference wether they copy of other books or not but there is sufficient knowledge to pass css. it may be a kind of propaganda against dogars books. yet seniors suggest other books as cotemporary afairs book of imtiaz shahid and pakistan affairs of ikram rabani and encyclopaedia of every day science of samo sahab. best of luck and good bye
