The TOEFL iBT assesses a person’s ability to use and understand English at the university level. Furthermore, this test is an evaluation of how well you can combine reading, listening, speaking and writing skills to perform tasks of an academic nature. It is scored out of 120 points (30 points per section).
There are no biased TOEFL test centers that want to improve their scores because tests aren’t scored there. TOEFL iBT is only scored through a centralized scoring network.
Scores are accepted by over 10,000 universities and other educational institutions around the world; this includes universities in Australia, Canada, New Zealand, the U.K., the United States, Europe and Asia.
