The new “Official Guide to the TOEFL iBT Test: Pocket ed” is now for sale. It costs $19 bucks and includes one practice test. Described as “time limited,” I suppose it is a stop-gap product that will be offered until the complete official guide is available in May. You can find it on the official TOEFL site, in the test prep section. I’ll buy a copy when I return home later this month.
One thing to keep in mind is that the guide can only be downloaded one time after purchase. This could create problems for individuals with unstable internet. The audio and practice test files for the current (now outdated) Official Guide can only be downloaded four times, but I’ve heard complaints from users who experienced connectivity issues while attempting to download those very large files.
