6. Previous related studies Many scholars have been done researches on TOEIC exam. In January 2003, a team of content and statistical analysis specialists was formed to consider a redesign of the TOEIC Listening and Reading test as it then existed. The test redesign coincided with an effort to investigate the possibility of making high quality TOEIC Speaking and Writing tests available to test score users as additional test components. They brought the test into alignment with current theories of language proficiency and provided more proficiency information that is meaningful to test takers and score users. In January 2010, in their dissertation “Comparison of Content, Item Statistics and Test-Taker Performance for the Redesigned and Class TOEIC Listening and 3 Reading Tests”, Chi-wen Liao, Natalie Hatrak and Feng Yu analyzed 14 redesigned TOEIC form and 22 classic TOEIC forms. Their preliminary results at both the item and test level along with the results for test taker performance revealed the close similarity in statistical characteristics between the redesigned TOEIC test and the classic TOEIC tests. They claimed that test scores on the redesigned and classic TOEIC tests are comparable, even though the two contain slightly differe nt item type structures. Though many researches on TOEIC exam and topics relating to it were done, there has been no study of grammar in the new TOEIC tests, especially ways of learning grammar for TOEIC exam. Nevertheless, the studies mentioned above are helpful to this study in terms of providing the theoretical background as they described obviously the differences of the format and test items between the redesigned TOEIC test and the classic one.
