Is "how is this a syllabus" correct? Can I use the article "a" in that question?
The situation is following: I've asked my son's history teacher to provide his teaching plan for this year. He sent to me a paper describing his teaching methods instead. Perhaps, it's a mistake. So I am writing a letter to him and asking him a simple question: "How is this a syllabus? It looks more like description of your teaching style instead."
So, is "a" in there okay?
