I dislike doing the same homework for twice.

The day before yesterday my English teacher told us that all students must do the same homework again. As we all know. Doing homework is boring for most students. It is more boring if we have to do the same homework again. Everyone knows that we have plenty of homework to do. Every night I have to work till late . During the weekends, there is not even time for us to do the things we want to do . So my English teacher, why do you still assign us repetitive homework?

Notes: A good try for your attempt. I have added 'so' to the last sentence as it reads more like an English sentence.

Your teacher must be wise and has high standards, someone can tell that from the abilities of her students.
