when i try to take the practice exam a pop up appear telling me to use pc not mobile with pandas or jupyter what can i do please thank you

Hello Eman, Thanks for reaching out! From the way you have described the problem, it looks like that you are being displayed the mobile version of the platform, instead of the desktop one. In order for the desktop version of the platform to display, you need to be using a resolution over 1280px. Here's what you can do, in order to fix the problem you have came across: 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 continue to be displayed the mobile version of the platform, please make sure to contact us! Kind Regards, The 365 Team

i have already made all this and the problem still exist thank you

Hello Eman, We apologize that you are still experiencing issues with accessing the practice exam! Here's what could help us to troubleshoot the exact problem: Have you installed any browser extensions that could prevent you from attending the video lessons? Such browser extensions are "Privacy Badger" and "Hoxx Privacy VPN" for example. Do you use VPN at all? Have you tried using another browser? Have you checked your internet connection? In some cases poor internet connection may cause such an issue. A screenshot! Before providing us with a screenshot, please make sure to open the console in your browser and to take the screenshot after that. In order to open your console, press the "Ctrl" + "Shift" + "C" buttons. After that a new tab will appear from where you will have to select the "Console" section. After that please make sure to take the screenshot, by clicking the buttons "Win" + "PrtScr" and make sure that both your console and the video player are visible in the picture! Hope this helps! Best, The 365 Team
