It used to be magnetic tape, but now it is mostly CD-ROM, which can be used in computers.
2, online download, but online is generally true questions over the years to have corresponding listening materials.
Moreover, listening and the original text are mostly separated.
I suggest you go to some professional websites to ensure the download quality.
For example: New Oriental English, Big Ear English.
PS: The new question type was only used from June 5438 to February 2007.
If you want to download the real questions over the years, I suggest you don't download the ones before 65438+February 2007.
Because the old questions don't have much guiding significance for the current exam.
Good luck with your studies.
