One of the best website for online classes

Coviu.com is an excellent website for online classes having both cloud and non cloud clients for all operating systems. Students interested in attending online classes can join classes as a guest student. So no need for students to create an account for attending online classes. However they can also create an account at https://coviu.com/checkout/register?next=%2Fstart and then login to class room for discussion. The class room is having option of text/audio/video chatting, whiteboard as well as application wise screen sharing. I have also created a class room whose URL is https://coviu.com/me/@pankaj-kumar in which interested students can login and start discussion in online class.
