Kota Factory (2019–2021) is a critically acclaimed Indian web series that follows Vaibhav Pandey’s journey through Kota’s intense IIT coaching culture. Featuring a standout performance by Jitendra Kumar as Jeetu Bhaiya, the show delivers a realistic, emotional, and motivational look at student life, academic pressure, and the pursuit of engineering dreams.
Vaibhav joins Prodigy classes in Kota mid-academic year, assigned to the struggling A10 batch after Maheshwari classes reject him. At his homestay, Meena advises against joining A10. Vaibhav appeals to Deepak, Prodigy's Head Manager, but is denied a batch transfer. Determined, Vaibhav meets Jeetu Bhaiya, Physics lecturer, who gives him a 50-question challenge to complete overnight. With Meena and Uday's help, Vaibhav solves 42 questions by copying solutions. However, he struggles with the remaining 8. The next day, Jeetu Bhaiya exposes Vaibhav's cheating, but impressed by his effort, offers a second chance. Despite the infraction, Jeetu Bhaiya promotes Vaibhav to the elite A5 batch, recognising his hard work and potential.
Vaibhav struggles to sleep, eat food at mess, drink water (which he finds salty) and study for long hours at Kota. Uday and Meena try to help their new friend but all in vain. One day, Jeetu Bhaiya acknowledges about his problems and helps him with the solutions. Eventually, within 21 days, Vaibhav has all the struggles sorted with all the help he has.
Vaibhav is not able to cope up with Inorganic Chemistry and blames the teachers who teach the subject. But even after changing 3 teachers for the subject, he bursts out all his anger and frustration in front of Meena, who then takes him to Jeetu Bhaiya. He advises Vaibhav to drop the subject.
Jeetu Bhaiya advises students to take a break from JEE studies and attend school practicals. Uday plans to explore Kota with Shivangi and invites Vaibhav and Vartika. Meena, initially planning to study with Vaibhav, changes her mind and joins Uday's outing instead. Vaibhav and Vartika study together, developing unspoken feelings. To be closer to Vartika, Vaibhav takes the Maheshwari exam, despite his reservations. They study together for 12th-grade exams. Meanwhile, Meena realises wandering Kota was pointless, developing feelings for Meenal. However, she reveals plans to move to the US, leaving Meena regretful for neglecting studies.
Vaibhav is surprised to be selected for Maheshwari classes. Deepak, Batla Sir, and Jeetu Bhaiya address the selected students, including Vaibhav. Initially, Vaibhav refuses, having settled into Prodigy. However, Jeetu Bhaiya convinces him to join Maheshwari for its larger student body and better focus. Vaibhav consults his parents, following Uday's advice, and decides to make the switch. Bidding farewell to friends Shivangi, Meena, Uday, and Vartika, Uday drops him off at Maheshwari. Vaibhav is allotted to A3, where he meets Sushrut, a nervous student from A7.
