i have seen a book of caravan which is compiled for css exam but it is not that much authentic as foreign books are. And as far as topics are concerned, these are dispersed in these books and you have to go through all the books i-e miller & harley, raven & john, reece & campbell, integrated principles of zoology, verma & agarwal, etc.
I ,too, have solved 15 years papers and have my own notes.
