For each question you include in an Exam Builder source file, you can provide a little information or a lot. Each question begins with a section heading containing the keyword Question, followed by sections in which you state the question and present a multiple-choice list of possible answers or a free-form response area. You can also include sections containing setup information for the question, the correct answer to the question, short and long explanations of the solution, and comments. Like the front section, Question sections can include comments that don't appear in the generated exam.
You can state questions using algorithms and introduce random variations so that the question statement and even the questions themselves differ slightly each time you generate an exam. Additionally, you can include several variants of the same question in the source file and have the Exam Builder randomly select the variant or variants to include in the generated exam. This ability to vary content algorithmically represents the real power of the Scientific Notebook Exam Builder. If you don't use algorithms to state questions, however, Exam Builder questions don't vary from instance to instance; each time the Exam Builder generates an instance of the exam, the questions are the same.
