Hi Sainath,

Thanks for the PR! I just talked a bit with the rest of the TSC members, and we may need some additional updates to this PR.

A couple of points:

• So we are changing the numbering back. Course 0 will be Course 1, Course 1 will be Course 2 and so on.
• In particular, Course 1 will only be a Course Setup course - so this will be the part detailing the toolings being used and how to use them.
• Course 2 will be the Learning COBOL, Course 3 will be the Advanced Topics and Course 4 will be Testing.

While this may results in confusion, we will also release a new major version of the course by the conclusion of this mentorship period (i.e. 3.0.0), detailing the changes made.

There are also several comments on the changes itself.

Again, thank you for submitting this!
