Separate grammar review should be incorporated if practice-tests are used. Or, maybe using topic-based textbooks is a better choice for low-level TOEIC preparation courses. More explicitly, sequential grammar review and phrase-level practice through ample examples may also be vital for those learners. Curriculum coordinators and course instructors should take these factors into consideration and look at the possibility of using different types of textbooks and implementing different ways of grammar instruction and activities for different levels of TOEIC preparation courses within a curriculum.
