This is a test format problem collection. There is writing inside. Please be aware of this. The CD is unused and unopened. As it was used in a university lecture, the writing inside can be used to improve your score, which I think is an advantage. After the lecture, I improved my score from 520 to 875. - Official TOEIC Listening & Reading Problem Collection 7 - Contents: Contains 2 tests (a total of 400 questions) - Accessories: Audio CD included
