[ENG DUB] Sorry, I Upgraded - Episode 5

During a critical exam, two students face off over which difficult question to tackle: one chooses the complex application-based problem involving fighter jet mathematical models, while the other opts for the more theoretical question. Suspicion rises as one doubts the other's past achievements, accusing him of cheating and questioning his confidence to pick the hardest question. When both end up selecting the same problem, they prepare contrasting solving methods to outsmart each other and prevent copying. However, a surprising revelation occurs when one realizes the other knows his four unique solving approaches, complicating the competition and leaving the outcome uncertain.
