Sample Exam Questions
Initial Exams
All questions are one best-response type, in the multiple-choice format. Each consists of a stem (e.g., a question, image, etc.) followed by a series of four or five possible responses or options. The examinee is required to select the one best option among those offered.
This type of question usually has a comparative quality, so that one answer is the best among those given. Other options in the set may be plausible or even partially correct, but not the best response or option.
