I am trying to set the answer type property to allow a numeric "10" and a alpha "ten" as an answer to a question using the simple, non-advanced assessment editor. Is it possible, or do I have to use the advanced assessment editor?
The only way to do it is with the help of the Advanced Assessment Editor. This can be found on the official website. I will link you directly to the editor, but you can use the menu on the left side of the page as well if you want to read more about this software and the way it works with the answers type.
