Exams are open book and notes. Problems will be similar to those you have done for homework. In discussion questions, be sure to direct your answers to the question asked. If you are asked to compare two methods, for instance, you should not simply describe method 1 and then describe method 2! And please do not copy passages out of the book!!
In calculational questions, show the work. I cannot give partial credit if the answer is wrong and I can't follow what you have done.
