This is an error with respect to the uploading of the sheets. There will not be any sheets uploaded. Very happy to hear that you are seeing visible changes in your dancing.
If you progress slowly through the playlists, instead of jumping from one to the other, it will be much clearer.
All the topics are introduced systematically and you will also be able to learn how to analyse a korwe and see where the aksharams/ utterances fall within an avartanam.
Try to watch the instructions more than once. you might have missed something.
You always have the choice of attending a live workshop sometime :-)
