How come the Cambridge's book for the TOEFL preparation is so much expensive (almost 100€) in comparison with the Barron's one (roughly 31$)?
The material seem to be nearly the same...
In my experience, Cambridge test prep materials are much more comprehensive. I haven't actually seen the Cambridge text, but I do use the Barron's and it is o.k. but not wonderful! You often get what you pay for.
Hope that helps
