I was happy to discover that Pearson has published updated print guides to the PTE Academic test (one for students, one for teachers). They cost $86 AUD a piece and only seem to be sold from Pearson’s Australian web store. But they do exist. Apparently.
I am still a big believer in print books because they can be stocked by libraries around the world. Libraries remain a major source of free test prep – the long reservation queues for prep books at many libraries speak to that.
