In most states around the country, there will be a basic guide for all the English classes in public high schools. This means that out of the 4 years, each year will have a specific focus and specific books that the students are required to read; for example, all of the 10th grade English classes at my high school were generally focused on poetry and most of our reading and writing had to do with that. This is completely different when you get to college, though, because it depends much more on the professor that you have. In my Composition 1 and 2 classes, we focused mostly on writing papers that the professor would design and we had to read one book in each of the classes. Compared to what my friends took, I would say there was much less consistency between professors.
