Thanks for your feedback, Richard!

Hey Jason,

Thanks for your feedback! I'll see how it can be improved in future.

I'm not sure I understand your request correctly. The english version contains comments in english. Russian comments are only in russian version.

I plan to add tests in the next edition of the course. Existing users will get free upgrade.
