Channel A's education solution variety show 'Teachers 3: Retake War' returns as a large-scale survival competition featuring 100 retake students, with the final winner receiving a full university scholarship.

'Teachers 3: Retake War,' an entrance exam survival reality program four years in the making, follows 100 retake students preparing for the 2027 academic year CSAT as they compete for their last chance, each carrying their own personal story. This season is set against the backdrop of the final CSAT before the entrance exam reform, with participants going through various missions and competitions to determine a single winner. The final winner will receive a full university scholarship.

The recently released premiere teaser video shows 100 retake students facing off at desks filling the studio. Participants expressed surprise at the scale of the competition, showing their determination with comments such as "Since this is my last chance, I think I can push myself to the limit" and "I will definitely survive."

The video also revealed various personal stories, including a retake student studying to find the cause of her sister's brain lesion disability, a retake student from a divorced family preparing for independence, and a retake student vowing to study harder for his father. Yoo Dae-jong shed tears upon seeing these stories.

Facing the 100 retake students, Jung Seung-je said, "I have to check whether their hearts are open or closed, and that's the hardest part," signaling that a moment of cold-hearted selection was approaching. He also asked one retake student, "Are you going to give everything up?" before pressing the pass button, saying, "I want to change your life once."

MCs Jeon Hyun-moo, Jang Young-ran, and Mimimynu, along with Jung Seung-je, Yoo Dae-jong, and Kim Ji-young, appear as the 'Tivengers' to guide the retake students' challenges and competition.

'Teachers 3: Retake War' premieres on Thursday the 15th at 10 p.m.
