Yes. Bad Genius has roots in real cases of cheating. The filmmakers used these real stories as a basis and built a fictional narrative around them to create an engaging movie.
Since it's based on a true story, the exact identities of the main characters might be a bit hard to pin down precisely. However, if we look at the movie that was based on it, there was Lynn who was really smart but got caught up in this web of cheating. There were also her friends or accomplices who were with her in this. And then there were the people in the school system like the examiners and teachers who were on the other side of this whole situation, not knowing that they were being outsmarted by these students with their cheating plans.
The 'Bad Genius True Story' is about a group of students who engage in elaborate cheating schemes in an academic setting. It shows how they plan and execute cheating during exams to get high grades.
