We know GMAT PREP is the most representative indicator of GMAT but for TOEFL which materials, I mean which tests are most representative of TOEFL iBT??
How do u evaluate the mock tests in Cambridgre Prep CD rom???? What about its difficulty level compared to real one!!
There is Official Guide for TOEFL and it is really good for predicting score in reading and listening. My tutor said that Cambridge is harder than real TOEFL. Anyway, I don't know how you can assess your speaking. Although, I remember that there was such opportunity at Official TOEFL site.
