We use Go To Webinar to deliver all our live web events. Go To Webinar is used world-wide and is considered one of the best quality systems for hosting online events. There is a possibility your school network will block this application. To ensure you can register and attend our live webinars from school, check the approval process with your Principal or IT team, and allow sufficient time for the webinar application to be made available on the school network.
Alternatively, if you have a personal device with data, you could use that too.
