What do you mean by WUZU?

From your narration, it's seems to be something prior to your goal.

And you're such a loving model for your siblings to follow, from your narration, there's a pop-frame image declaring that you always take charge of your siblings, ensuring that they are good to go.

That's an attitude embraced by a good disciplinary material. You should be boast of having such a grade.

Wow!! You also added that it's not easy to teach 30 students, it simply shows that you're a care-guilder. You must be a teacher by profession. Anyway, I wish you the best of luck in this contest. Congrats @arinaz08
