I don't assign specific nightly homework exercises (the kind of daily practice you might receive in math class). The out-of-class work you do for English class will be more project-based. For example, if you have been asked to write a script based on a short story we have read in class and it is due next week, that is your your daily homework until the due date. Brainstorming on one night, writing for another, editing the next day, taking a break the following day, reading it aloud to a friend or family member and getting feedback for another and polishing it the day before it is due. Some students do not take this approach and procrastinate. They leave the assignment until the evening before it is due, rush through it and create mediocre work. This results in mediocre grades.
Wondering why you procrastinate? This article answers the question.
Are daily homework exercises useful anyway? Here's an article that ponders the question.
