I had the TOEFL exam a few days ago. I got 27 in writing, 25 in speaking, 26 in listening, and 17 in reading. Although I was able to read all the text, in the reading section, almost easily, the reading questions were very tough and the four-answer questions were similar to each other, and was pretty tough to take the right answer in 30 seconds for each question.
I believe, it is because the source that I was practicing on, was not commensurate with the rate of difficulty of the real exam. Even ETS website free practicing questions cannot demonstrate the difficulty of the real exams. I live in Iran and cannot purchase authentic practicing materials easily, although I can do that with extra effort. I just want to know if anyone can help me or introduce any other resources that represent the real difficulty of the questions in the exams. The TPO simulator provided by institutions in Iran does not represent the real difficulty of the exams in the limited time span. Any other suggestions will be welcomed.
