Hello Mohra,
I work in Kiron Open Higher Education in the Student Support team. I hope you were able to complete the edX course. I suggest going on the Kiron Student Forum (forum.kiron.ngo/) and reading what other students have posted/ask questions there as well. There you can interact with other students from your study track. Many of your questions have already been answered, and there are great comments for you to read.
Kind regards,
Kiron Student Support
