THERE are a few important differences between the structure sections of the new computer-based TOEFL exam and the old paper-based exam. The kinds of questions are the same, but the computer-based test offers fewer questions. More important, the questions on the computer exam will be selected according to your level of pro- ficiency. Your first question will be “average” in difficulty. The next question will be easier or harder, depending upon how you answered the first question. The rest of the questions will follow this pattern. Throughout the struc- ture section on the computer-based test, the level of difficulty of each question will be based upon your answer to the previous question.
