All students in a class cannot take an oral exam simultaneously. This means that either: * everyone gets the same questions meaning later students can cheat by asking earlier students what was on the test, or * everyone gets different questions meaning much more effort to design the exam and big risks that some students will get easier questions and others will get harder questions
