TOEFL test is not a test of how well you know English, it is a test of how well you know TOEFL.
Test of English as a Foreign Language (TOEFL) is a standardized test to measure the English language ability of non-native speakers wishing to enroll in English-speaking universities. It is accepted by most academic institutions globally, including the top universities in the world.
The TOEFL test is a barrier that stands between you and your future dream university. It tests for specific language skills used in the academic environment which can differ to a great extent from what we consider ordinary, every day English.
Knowing what to expect in an unfamiliar environment is the first step to success. A well-structured, detailed and comprehensive preparation will go far in helping you get the tools and skills you need to overcome this challenge and move on with your life.
