I'm a contract professor at uni. I think that he should put which kind of students you are teaching C to.

I am their first experience at university and for some of them C us their first programming experience.

In this case my only advice is just keep repeating the same subject in more than one lesson.

What is suggested into the article seems to me more about "how do I run C in production".

But good suggestions anyway, I'll review them to see what I could use if it makes sense maybe when we do lab.
