Sony LIV is set to release its long-awaited original web series 13th on 1st October 2025. Inspired by the life and vision of famous educator Mohit Tyagi (MT Sir), the series uncovers India's extremely competitive exam-prep culture. The title "13th" suggests the "drop year" after Class 12, when thousands of students focus on cracking the IIT-JEE entrance examination.

The focal point of the series is the mentor character, Mohit Tyagi (MT Sir), one of India's most celebrated teachers, whose efforts in providing free high-quality Physics, Chemistry, and Mathematics tutorials on YouTube have impacted more than 20 lakh students. His channel, which is followed by more than 2.2 million students, offers systematic, deep coaching within the reach of students all over India, from Kota to small towns. Where families spend lakhs per year in Kota, Tyagi provides the same depth of coaching for free, underlining the true worth of access. Over two decades, his consistent approach has produced many Top-100 ranks, proving that the focus is on habit over hype. By making world-class coaching accessible to students from diverse economic and social backgrounds, Tyagi has redefined the term "mentorship" for India's education in a whole new way. Turning down crore-level salaries, he opted to serve students through free education. As opposed to business platforms, Mohit Tyagi created a movement based on discipline, consistency, and long-term student interests.
