This application contains class 9 science mcq chapter wise with brief description . This application is design for class 9th student each chapter contain detail solution with chapter wise. This application contain 15 chapters. Each chapter deal with hot mcq. I think this app is must have app for class 9 student.
This app contains solution of all the chapters included in the class 9 science mcq.
This application contains:-
