Here is a list of all the Facebook groups for the different IB subjects, for students. There are also a number some groups listed for parents, teachers and current MYP students.
We've set these up ourselves, as people have asked for them. But, if we've missed type of group that you think is needed, please let us know in the comments below. Please only join the groups you're most serious about (i.e. what you really want to do well in or that you are working hard to improve in). All members of these groups are asked to contributing to the group.
