- If the teacher is absent, he can teach remotely by using his avatar for live presentation
- If some students are absent, they are free to attend the class online on the Facebook group
- The lesson is composed by tweets. At the end, the Q&As session is held on Quora.
- Students chat between themselves during the class on Facebook, posting on each other's walls and commenting
The challenge is, define x! :)
