Thank you for viewing. This is an official TOEIC test practice book. It includes the answer key/explanation section and one CD (originally two, but please note that only CD 2 is included). While not the latest edition, it's a good way to practice by working through a lot of questions. The inside is in good condition with almost no writing. - Title: TOEIC Test New Official Practice Volume 3 - Included: 1 CD - Contents: Answer Key/Explanation Section - Publisher: Institute for International Business Communication
