These Lessons are based on Virtual Learning (live teaching from the studio and the students/teachers of 165 spread different parts of the country watch on the television and other equipment's installed at their school with the assistance of government) through NCED, Sanothimi Bhaktapur. We believe, no time and space can limit the learning process. This channel includes the recorded version of the same videos (the videos from live teaching) and we hope that it will be helpful for students and teachers from other schools as well. Our teaching is not the MODEL and we don't claim that the way we teach is the best one. All the videos are based on the curriculum and textbooks . When you watch the videos you must take reference from the respected subjects' curriculum and textbook as well. We welcome your constructive feedback.
