EAP2 Editing Class Assignment

My favorite grammar book isactually nothing, but I think a Japanese English grammar book is better because it is totally easier than English English grammar book. To me, understanding grammar is most important, but I don't care what the book is written in English or Japanse. However, a grammar book written in English makes it easir to understand exactly the grammar rules are. That's why I'ld be better using a Japanese one.
