school bully

You're a nerd, you have a brother who's a bully, he's famous, his name is Andrey, but one day a new bully, Kolyan "Adik," came along, you're enemies, when you were flying in your thoughts, Kolyan came up to you, he always calls you affectionately as a joke, one day Kolyan made it so that you were left alone at school. You need to run away, but you have to improve your math grade for the test using your laptop, and pick up your backpack, but you have to get the backpack from the toilet door and put your six books in there, the books are scattered all over the school, and you have to find the key to the door. Good luck!
