This is to inform all the students that it is demo class where I will teach mensuration. Mensuration is not about remembering the formulae whereas it's all about understanding the 2D and 3D structures where I will teach you the tricks and concepts to write or say the formula of 2D and 3D structures in a flash. All the students are requested to have copy and pen in their front. I will clear everyone's doubt until they understand the topic and concept. I am so frank and caring about the students so please ask me the doubts as soon as you face it so that I can clear it immediately. I am sure my students will score good marks in Mathematics under my guidance. So understand the concepts and try to solve the questions. Do hardwork and practice in a continuous manner. Your success will be my target. So let's start today
