Please if someone could clarify my confusions regarding case laws. How important are case laws for May attempts? generally i have heard amendments for May and case laws for November are important. Are case laws given in the recent case laws book by ICAI and RTP enough? Also if some of them have come in earlier attempts, do they still stand a chance to repeat? Can i also ignore case law based questions given in PM presuming they would never repeat?
