I'm currently taking a course called Legal Drafting. Every other week we take a three-hour exam from real Bar exams. They consist of the Performance Exam section of the Bar. You're given an assignment (write a memo, an appellate brief, etc.) called a task memo. You're provided with two stapled packets: a Library of cases and statutes, and a File, consisting of lower court briefs, deposition testimony, etc.
Our professor instructed us on the first thing we should do when we get the exam: tear off the task memo sheet.
"Why, you ask, should you tear off the task memo?" He demonstrated with a powerful flourish the ideal motion. "First, because it will help you avoid 'mission creep.' Mission creep is when you lose track of the assignment. Secondly, you should tear off the task memo because it will freak the hell out of everyone around you."
