If students applied themselves to their work, the quality of their papers would improve. They don't seem to realize that every discipline requires communication skills. I do not believe that the importance of good writing is stressed enough. If students were taught how important writing is, perhaps they would take it more seriously, and devote more time to learning writing skills. The basic rules of the English language never change.
Subjects still receive the action of the sentence, verbs are still the action words.
Remedial classes are built for those who have an exceptionally hard time grasping the concepts of a discipline, and usually, there are fewer people in the remedial classes than there are in the regular classes. But in English, students can take the same classes through almost all of their career. In my high school, English 9 for freshmen had the exact same curriculum as English 12 for seniors, and these were the classes that were always full. These are the remedial classes. No one takes algebra 1 from 9th to 12th grade unless they have a really hard time, but no one thinks it odd that a student can take the exact same English classes most of their lives.
