Is the TOEFL predictor accurate?

Quite accurate, that is, there are a lot of topics, and the ones on that day are relatively accurate, but the time is usually tight, and the exam will be held before I have time to read it.

At that time, I read the composition of the machine classics, which seems to be downloaded from "Pony Crossing the River". I got it in my composition and looked at the train of thought. It is still very useful! !
