I find the green tick under the user's answer in the quiz Full Statistics page misleading when the user selects the wrong answer to a Single Question type question. Ideally, it should be a tick if the user selected the right answer and a red cross if the user selected the wrong answer. However, the current program only has the one graphic for both.

As a compromise, I think it is better to use the image of the radio button here. Since the same graphic is used for both the user's answer and the Correct answer, changing the graphic for one will change both. However, I still think this looks far better.

Since the graphic for the radio button is generated internally, I have created a png file that can be used instead of the tick.png file - see attached png of a selected radio button on a transparent background.

All you have to do is replace tick.png in <joomlaroot>/administrator/components/com_ariquiz/images with the attached tick.png file.

ETA: I can't upload the .png file as an attachment because this file type is disallowed. However, you should be able to copy the image from here:
