Hey, I urgently need book recommendation for the said portion of pol.science paper. I have read a few books but none of them have satisfactory content about Pakistan's constitution which could actually help in preparation for the papers. Like there are no clear and minutely detailed topics which is requirement of the exam. For example I couldn't find sufficient material on provincial autonomy under 18th amendment and comparison of different constitutions of Pakistan. So I would be very grateful if anyone can recommend me a book which is clear on such topics.
