Write an essay on virtual teaching

Dear Student,
Such questions are meant for the development of your creative writing and hence must be attempted by yourself. 
Here are a few pointers for your reference:

1. A way to make knowledge available at the door steps of the students.
2. Low cost of education.
3. Distance education-a good choice for those who are working full time.
4. Extra help available to students through educational web sites.
5. Variety of study material available on educational sites.
6. A student can learn as per his convenience.
7. No restriction of time and place.

Hope this helps!
Regards
