Hola Ian,

Students are never marked wrong for punctuation unless that punctuation is part of what is being tested, for example, you need to include accent marks to write correct Spanish otherwise you change the pronunciation or meaning of the word (see Written accents in Spanish).

I don't know which question you are referring to, so I'm going to use a French example I have handy to answer your question about "being marked wrong."

When you look at your answer page, you see something like "Almost there" and your answer will have a "hollow" green check mark compared to the "correct" more solid green check mark

If you hover over this "hollow" checkmark, you'll see it says "Don't worry, we scored it as correct"

So please let me reassure you that if your only mistake was forgetting the question marks, then you scored "correct".

Saludos

Shui
