The exams will be open book. You should bring the textbook, or you will be at a serious disadvantage.
You cannot share books with someone else. You can also bring any other books, notes etc. you want,
provided they are on real paper. No electronic devices of any kind are allowed in the exam. No sharing of
any materials, resources, stationary is permitted.
