Hello Madam, I trust your doing well. I have found your course is the best enhanced and well understandable course for people like those who don't know polity, history and ecology. I have stopped following multiple resources and stick to your lectures, also the books of the course for external reference only. I understand its hard to cover all the topics from the book but I request you to provide some hints about skipped or unimportnat topics which are not coverd in this lessons or may suggestion us to do it as a home work ,it will help us a lot cover whole subject. Otherwise the focus will slowely dimishes. I hope you grasp what I mean. I heartly thankful to you for contribution to the society.
