I often tell people to consider joining university societies (or student clubs) in order to take a break from academia and to do something in their spare time other than drink and party. Societies and clubs at university are a diverse collection of groups and organisations ranging from sports teams to hobby organisations to political and liberation groups.
If this is something that you are considering joining when you get to university, take my virtual hand and let me guide you through the minefield that the world of societies can be.
