would diligent work here?
In English "hardworking" may also be two hyphenated words - i.e. hard-working - for which I get marked wrong!
You may get a warning, but you won't be marked wrong :)
What form would a "warning" take? As far as I can see, it could only be marked as a typo.
Yep, it should mark it correct but show a message saying "You have a typo in your answer" :)
Thank you, Joanne.
