The Quiz, when previewed, is displayed on 50% of my screen, and the remaining 50% is white space on the left. How do I change the frame size to full to utilise the entire screen space ?
I do not see this problem on my Moodle site, Quiz uses full screen.
Which Moodle theme are you using?
Moodle 3.9.1 using the default theme provided by Moodle
