Hi Moeffin Bin Jasit ! Thanks for the link! We can confirm there is an issue with the MCQ not loading correctly on some Android mobile browsers and are currently working on a fix.
In the meantime, you should be able to view the questions by viewing it in desktop mode from your mobile browser (or preferably from a computer if you have one).
To do so, click on the menu button at the top right of the browser and enable the option; Request Desktop Site.
Do give that a try and if you are still having issues, please email us at support@openlearning.com with your account details so we can assist you further. Thank you!
