Since we come from very different backgrounds, our knowledge about different topics may vary a lot. In order to make sure we all start the intensive course on the same page, we prepared a small packet of prematerials that should cover the possible differences. For some of you the topics may seem rather easy and some rather unfamiliar, but everybody should find something new from the texts. After reading through the material you can be sure that you can start the course without worries about either basic knowledge or language skills. Please get to know the material carefully. There will be a small quiz closer to the course and reading the material through in one night is not exactly the optimal solution.
