Hello, I hope it's not too late. Almost all learning platforms are more geared towards beginners. Besides, everyone learns at different speeds. For me, the right idea would be to introduce something like Chinese class (https://www.chineseonlinecourses.com/) (as on other platforms) to sort students according to their ability level. That sounds like one of the best options for me. But it would be hard to implement.
