Khan Academy English (CBSE) was created 2 years ago and hasn’t been updated. A lot of new videos have been added since then, many replacing the old ones.
Yes - there are definitely new resources available. We’ve been working on doing updates for all of the Khan Academy channels, as well as adding channels in new languages (such as Kannada). This has involved some changes in processes and work with Khan Academy to better handle these updates, as we have hit issues with our previous approach of downloading videos from YouTube.
I am hopeful that we will be able to update these channels in the near future, but there are a couple of outstanding issues that still need to be resolved to finalize the updates.
