That's Cunning! Shijo Saidai no Sakusen is probably the best movie about cheating on exams that you will find out there and it's definitely worth a watch! Even though it is over 20 years old, the comedy in this movie has aged really really well and it's still freaking hillarious on what kind of absurd and creative cheating techniques all these students come up with up. If you want to have a good laugh or even just some inspiration on how to cheat on your exams (hey I won't judge you), then you should absolutely watch & enjoy this movie!
