Je ne suis pas experte en anglais j'aurais répondu cela :
For being a better student, i'll have to be more organized. For example, i'll need to tidy my room to study in a clean place. I must write all the homeworks I have to do, in this way I won't forget to do them. If I want to stay concentrate, i'll have to turn off my phone and my computer. I also must be silent during the lesson to understand it better. I can help my friends when they have a problem to do an exercise. I can look up in my dictionary to know what's the meaning of the words i do not understand.When I can't see what's written on the board, I can ask if I can draw the curtains or if the teacher can turn on the light.Of course, I will always be respectful with my teacher and the pupils.
Voilà, pas sûre d'avoir fait les 80 mots, mais j'espère t'avoir aidé.
