Exam preparation

I have to admit that a "Mayball" lasting from 9 pm on friday until 6 am on saturday is not exactly the best preparation you can think of.
But still the afternoon today was quite efficient with preparations for International Management. One website I stumbled upon and I would like to share is businessballs.com. It sounds a bit obscene and the design is awkward and the usability poor. But it convinced me with a very likeable concept, neatly summarised and easy to understand content, no advertising, and a clear ethical purpose. Happy preparations.
