Please ensure that your device is supported by checking here, this could be why the course isn't running properly for you.
If your course is freezing or crashing this is likely due to a drop in connection.
To test your internet connection, go to www.fast.com
Wait until the speed test finishes, and you should see your result like this:
Your speed will need to be above 5 Mbps in order to run the course without issues. (Kbps is slower than Mbps)
If your internet speed is below 5 Mbps, you will not be able to run the course without issues and we cannot guarantee that you will be able to complete it.
If your internet speed is fine, this could be down to a drop in your connection, even the fastest of speeds can drop for a second or 2. It might be worth refreshing the page, and trying again.
If this still doesn't work, it could be due to our site being blocked, this is especially common in schools, hospitals and offices with strict IT settings.
Once whitelisted, give the course another go, this should hopefully fix your issue.
If your course pages are still freezing, please submit a ticket or call the Highfield Support Team on 01302 363 277
