Science - Chemistry

dVIDYA course materials are contained in about 1/4th of the regular volume of the course materials (Books and Video Tutorials), vastly  reducing load and stress on student,  and improve their scores in Tests. 

dVIDYA covers a large number of courses in various streams. Development of course materials for such varied subjects would naturally take time. Our team of Authors and Technicians are working hard to upload the Books, Tests, Quiz, Video Tutorials and other materials, at the earliest possible. 

Meanwhile, for the benefit of students, we have curated some good materials (e-books & Video Tutorials) available free on NET, and compiled the links for each chapter. Just click on the link and continue your studies, without waiting for our materials to get uploaded.

At dVIDYA, learning is FREE !
