Leave the questions on a line by itself. Write out the correct answer yourself. Use your version to help you revise the question, as needed, and to estimate how much time students will need to complete the question. If you can answer the question in ten minutes, students will probably need twenty to thirty minutes. Use these estimates in determining the number of questions to ask on the exam. Give students advice on how much time to spend on each question. Decide on guidelines for full and partial credit.
