    Description

    The videos herein are strictly based on Nepal CDC curriculum, promoting e-Learning in Nepal and are made with intention to provide guidance to the Class 9 students, for securing good score in finals. The course tries to cover all the basics of Algebra, Limit & Continuity, Matrix, Co-ordinate Geometry ,Trigonometry, Vector and Transformation along with solution of most frequently asked questions with fundamental theories and numerical needed for completing Class 9's Optional Math. We strongly believe that, viewers will be benefited from these videos and the thirst of curiosity of viewers will be quenched! Feedbacks and suggestion to improve are always welcome and highly appreciated!
