Last year, I made a textbook if you didn´t know. More info, PRESS ON TEXTBOOK TAG
This year, I updated, made changes and correct mistakes for this year.
Note: This is homemade and without any comercial relationship with any publisher company.
Note 2: I eliminate the Unit 5, because honestly I never make it that far. In Sonora, we end the school year 3 weeks earlier than the rest of the country, and minus 2 weeks in the Winter Break and 2 other weeks in the Easter Break…. Well, I’m lucky if I finished the Unit 4.
Note 3: It’s designed to be printed on both sides of the page, except for the cover.
