You can use HTML instead of plain text to write the details of the question and any supporting material (for example, hints, comments, or a worked solution). Use HTML to apply formatting to your text (for example, bold, italics, or a font), or include images, tables, or links to other file resources.
To use HTML:
Add or edit a question in the Question Bank Editor.
On the Question Name & Type screen, select the Use HTML check box.
Note: Every form in which you enter details has a Use HTML check box. For example, you can choose HTML for the hints, while using plain text for the question, comments, and solution. This check box sets the default for the other check boxes.
