Answer 1

Hello Henry,
Are you having difficulty with a lesson? I would first suggest you to checkout the lesson comments, usually people talk extensively about lesson subjects in there.

If you still doubt something then you are welcome to ask in this forum, but please also mind the guidelines for posting a question, two of which were to specify language in Relevant Tags section and include the lesson link in Description section (see below post on how to share links).
