Where to ask doubts

Hi G.G. Thirupthika,

Unfortunately, the app does not provide a place for questions and comments on the videos. However, when using the desktop version of Khan Academy, you can ask questions and posts comments beneath the videos and articles.

Let me know if you have any further questions! 

hi Evan Lewis,
I am using the desktop version and I don't see any place to ask questions and doubts. So, where do I ask my doubts?

Same problem....
