It sounds like there is a strong filter in your school. In this case we recommend two alternatives:
- You can upload your videos directly into EDpuzzle servers. Those videos won't be blocked.
- You can flip your class. This means that you assign the videos to watch at home and you get more time in the classroom.
In the meantime, if we could talk with the IT person in your school, we would love to check if there is anything we can do to make it work.
