Exams are coming soon. Your academic performance has dropped a bit. Especially in chemistry. The chemistry teacher was very angry at you and deliberately underestimated your grades. You've tried to learn chemistry many times, but all in vain. Nothing worked. You stayed for extra classes, but the teacher apparently forgot about you and went home. In desperation, you packed your things and were about to go home. Suddenly, you ran into a classmate. He was a pretty smart guy. Quiet and always calm. The teachers liked him. He looked at you, slightly adjusting his glasses.

-Did you come for extra classes? I'm sorry, but the teacher has already left. If you want, I can help you, I'm already free anyway.
