It is up to you how regularly and for how long you connect with your Skype partners. The only requirement to count as a “connection” is that you are connecting your students with another school anywhere in the world. While it will take some participants a few months to complete the challenge, it might take others several years and different student groups to connect with 80 schools. There is no time limit nor pressure to make a certain amount of Skype connections in a given time period.
