Structure and Written Expression section of the TOEFL® test.

The Structure and Written Expression section contains sentences that test your knowledge of important structural and grammatical elements of standard written English. These sentences include a variety of topics and give no particular advantage to individuals in any specific field of study.
When topics have a national context, they refer to the United States or Canadian history, culture, art, or literature. However, you do not need to have a prior knowledge of these contexts to answer the structural or grammatical points being tested.
In doing something, in order to get the best result we need some tricks. This is supported by a wide range of knowledge and information that can be obtained from anywhere. Likewise, in doing TOEFL particularly in section 2 that is in the structure and written expression. Hence, when we do not get suspended above 500, one of its factors on the structure and written expression we obtain a total score so small that affect our score.
