I can't able to attend the exam.

Hello Mayuresh,

Thanks for reaching out.

If the system is displaying you that you need to switch to a desktop device, but you are trying to attend the exam from one already, you can try the following suggestions from our developer team:

You can increase or decrease the zoom level – both text and images – of pages that you view in Safari on macOS Sierra. Safari will remember your settings, until you clear your History.
To increase the zoom level, press Command-Plus sign (+)
To decrease the zoom level, press Command-Minus sign (-)
To change the scale(zoom) level press the "Command" + "0" buttons

If your laptop is using Windows, you can increase or decrease the zoom level on the platform by:
Zooming out the view on your browser. In order to do that, click and hold on the 'Ctrl' button on your keyboard and then press the "-" button in the top right of your keyboard
Try changing the resolution of your PC from "Display Settings" option. In order to select this option, right click on the home screen of your PC and select the option "Display settings". From there a new tab will open, from which you have to look for a section named "Scale and layout". In it try selecting the option "100%", which is recommended for Windows.

If you are experiencing any other issues, feel free to contact us directly through the "Report a bug" button or the Q&A Thread.

Kind Regards,

The 365 Team
