This Channel initiated by Dr. D. R. Vij (former Professor of Physics, Kurukshetra University, India) primarily aims at taking free education to the doorsteps of learners who for various economic and social factors can not avail benefits of regular coaching.

In view of the congested classrooms coupled with hefty tuition fee, social taboos and hazards of travelling (for girls in particular) this mode of extending education had become a necessity.

This self-learning approach is a definite step towards democratisation of education i.e. taking education even to individuals who staying in remote and far off areas were being deprived of education for no fault of theirs.

Viewers are requested to click LIKE button if they like a video and SUBSCRIBE to this channel to get notifications of more video lessons being uploaded from time to time in future. They are also requested to SHARE videos with nears and dears who can be benefitted.

All video lessons are systematically indexed on the website: www.gianmandir.com wherein one can register free of cost. All videos are also available through our “Gianmandir” APP which can be downloaded from Google Play Store.
