Familiarize yourself with the TOEFL format
Most countries now offer the Internet based TOEFL (iBT). A few offer only the paper-based test (PBT). Make sure you find out which test you will be taking before you start studying for the TOEFL. You cannot choose to take the paper based test if your country offers the iBT. One reason people experience exam stress is because they don’t know what to expect before a test. Prevent stress on exam day by studying the format of the test in detail. ETS has very clear standards about the format of their test. This is why it is called a “standardized” test.
Learn academic English
TOEFL is used for a different purpose than other ESL tests. The TOEFL measures your ability to succeed in an American university or college. Other English-speaking countries also require TOEFL scores as a prerequisite for admission. You don’t have to know about the business world as you do in the TOEIC test. Instead, you should concentrate on studying language that you would hear and see on campus and in the classroom.
In other words, you should read textbooks, encyclopaedias, journals and research articles rather than advertisements and resumes. You won’t need to know any background information about certain subjects, but it will help you to become familiar with the presentation and language used in academic material.
