There's a lot to learn from the lectures. Each chapter has keywords to study, and it's great that you focus on those and include code writing as well. The current popular post - the 36-minute lecture on Consumer implementation was a bit difficult to get through, so it would be good if you could upload the lectures divided into smaller segments. Just improving this part would make it much better. Students can divide it up themselves when listening, but it would be more appropriate to have it organized as separate lectures.
