The Open Library now offers a copy of Compass Publishing’s “Mastering Skills for the TOEFL iBT Advanced (Listening).” You can borrow it for an hour, or for a couple of weeks with a free account. Here’s a link. You can quickly access the audio files from the publisher.
This is a great book full of accurate listening content that will be new to 99.9% of people reading this blog. The book is from a Korean publisher, which means its content is way more accurate than most TOEFL books and websites.
Even if you ignore the skill building content, this is a great opportunity to complete two full listening practice tests. And, as you probably know, everyone ought to complete all of the practice tests they can get their hands on.
I check Open Library every day for new TOEFL books. Most of the time I am disappointed with the selections, but I got really excited today when I saw this one!
