I was attempting to import a maths exercise from Khan Academy (English) into my own private channel that I use for testing, called Watobe Test. The problem occurs with all maths exercises from Khan Academy, and I’m guessing that this is because they’re actually hosted on khanacademy.org rather than on Kolibri Studio? The only way to view the question content is in fact to click the Preview link, which takes you to a khanacademy.org URL. See screenshot below, with the hosting URL appearing in the bottom left of the image.
I’m guessing your implementation simply creates placeholders for Khan Academy questions (16 questions on Binomial Expansion, in this example), and then lets KA serve them to the user in their preferred order? If so, I can understand why there is no delete, edit, or re-order functionality within Kolibri. Let me know if that’s right.
