Completed chapter 1. But i again starts from first. is there any indication on chapter completion?
If I understand your question correctly, yes there is indication. The course page says when the next chapter will unlock.
We currently run our courses from week to week, and the next chapters open on Tuesdays at 1500 UTC.
Congratulations on completing the week early! You’ve put yourself in a better position that some of our students, and that is indicative of success in the course.
