I've decided that I'm not comfortable charging for access to these resources (and there are a good many of them, built up over several years). It can be depressing making all of your online teaching income based around a loathsome English test, and it has always irked me that the people needing that test result are often some of the most disadvantaged people in the world.
Hence, all of my TOEFL iBT practice test materials, tutorials and sample answers are now 100% free for all learners and teachers to access.
Hope it helps.
