Do all the questions have to be answered on the exam or can some answers be blank?

English language exams:

You must answer all 100 questions for your examination to be scored. Adaptive testing does not allow the tester to go back to a question once they have moved onto the next question. See the answer to Question #2 for additional information.

Foreign language exams:

Exams in Chinese and Korean are administered in computer-based, linear format. This format allows candidates to go back and review their answers once all questions are completed. See the answer to Question #2 for additional information.
