The video lessons are highly useful for students of classes X, XI, XII and degree courses. The colourful, eye-catching illustrations and animations would definitely kindle your interest, enhance your ability to understand the concepts easily, clearly and thoroughly. This would also enable you to realize the concepts, assimilate the ideas and take you to greater heights. Lesson Preparation, Presentation, Animation and Video Editing were done by Mr. B.
