Top 20 reviews twenty grammar areas that are essential for good English writing at the intermediate to advanced level. In the review in Top 20, however, emphasis is placed on helping students to notice the gap between their own language and correct English. Therefore, the focus of Top 20 is for students to produce and edit original pieces of writing as they learn how to find and correct common grammatical errors. Depending on the class level and the amount of writing and work that is done outside of class, there is enough material in Top 20 for seventy to ninety classroom hours. However, if time limitations exist, the material could be covered in as few as forty-five hours with an advanced-level group, provided that many of the exercises are done as homework. This book is designed for intermediate to advanced students. However, the passages in many of the exercises are from real textbooks that were written for native speakers. Thus, students will have to understand the grammar points well to be able to apply them in the exercises. For many students, a major obstacle to future educational plans is not being able to write effectively and easily in English.
