Information On Swedish Universities: ?

Hi,
Could we use this place to talk about your experience in Sweden. I'm considering going for an undergraduate course there but would like to know more about the country, studies, jobs a foreign student can do and any relevant information. .Please if you are a Nigerian studing in Sweden I would appreciate it if you share your experiences, what kind of work you do to help yourself and at the same time schooling, the language, how friendly are the people, NIgerian students there and many more.
Thanks
