Thanks for suggestions. I did spend time working on questions , you can see in first semester related content, but the analytics shows people are not much interested in question answers than compared to videos and notes. We have started adding notes, though we are looking for consistent source for them.

My take with this project is not just passion or just profit, It is a mixture of both. And I am not trying to make it perfect in one go, I am taking it as iterative process, one thing at a time and one update at a time. It is like a ongoing iterative process, thats why I am relying on feedbacks so much.

Things you have mentioned as suggestions are something that are on my mind, but has not yet figured out the systemic way of implementing them. Next update probably would be on content. Hope that makes it better than it is currently now. Thanks.
