     Just the mention of the TOEFL, GRE and GAMT exams brings a thought of long hours of dull paper work.

But that idea is becoming increasingly out of date. As planned, computerized tests will begin next year which

will bring a series of changes from test psychology to scoring techniques.

     From computer-equipped rooms, examinees will answer the questions on a computer. If they are sure about

their choices, they can pass to the next question by pressing the entry (条目) "next". Then another question

will be randomly (任意地) selected from a vast test item bank and appear on the screen. After answering all the

questions, examinees can choose the entry "quit" if they are not satisfied with their performance or "score" if

they want to see the result. Scores will be calculated immediately and appear on the screen. By that point,

student's marks are official-there is no going back.

     Since they greatly shorten the painful waiting process-which used to be two or three months, computerized

tests have won worldwide popularity. Besides, there will be no rushing to the registration offices (登记处) for

these exams. Computerized tests will be given every workday in an exam center with all three kinds of tests

being held in the same room. All test takers need to do is to call the exam center and book their seats for a

particular day.

     In addition it will become technically possible to apply new testing procedures. In the past, each examinee

had the same set of test items despite differences in their ability. Under a computerized system, however, if the

computer judges an answer is right, a question of a relatively difficult nature will follow. But if an examinee

continues to give wrong answers and is judged as un-qualified by the computer system, he will be automatically

denied the chance to go further in the test.
