(Important enough to warrant a separate message I think.)
I: The exam is open-book: You are allowed to bring any books/papers, in any language, with or without notes/annotations (yours or anyone else's).
II: You must justify your answers. An answer without calculations is not that much worth. And it must be legible. It need not be calligraphic, the grading committees know very well that you are working under a time-constraint, and they have seen all sorts of ugly handwriting. (Also, don't try to bluff by switching to illegible handwriting on what you do not know, they have seen that too many times too.)
Good luck!
