Studying frequently tested grammar points as part of test preparation is generally considered effective or necessary when it comes to Test of English for International Communication grammar review. Many so called "English study" books and magazines recommend using the official guidebooks consisting of previous tests as the best materials for Test of English for International Communication preparation, even though this approach assumes that learners already know basic English grammar and vocabulary. My experience both as a learner and teacher of English tells me that using practice test questions for grammar review works well for advanced learners who need to do more practice to review some grammar points and vocabulary. This approach, however, seems to pose difficulty for low-level learners. Since low-level learners often lack basic grammar knowledge, practice test questions give them the impression that they are exposed to multiple, unrelated grammar points all at once. It places more cognitive demands on the students; they easily get confused and are not able to sort out the various grammar points presented in different questions. Thus, grammar review becomes more difficult for low-level learners when the practice-test approach is taken.
