ULW in one year

Would it be possible to complete book 2 in one year? I’ve been using another program with my 7th grade son and he isn’t grasping it well. I will have him at home for only one more year then he will be going to public high school for his freshmen year. I know cramming isn’t beneficial and I’d rather keep him at home, but it isn’t my decision. I’m feeling hard pressed to make sure he’s prepared for high school English.
