It's a super funny movie. Though it is not a popular one. It's not even popular in mydramalist. The story is good. It's about cheating in exam . In short the story goes  like this-all student of dorm must got A  to save their dorm from demolition and how unique ways they can find to cheat in exam. It is my first Japanese live action movie and i thoroughly enjoyed it. What i liked is that they it is a pure comedy movie not a romantic comedy which is very common today. Main characters  and villain who is a evil professor acted very well. Music is okay. What i really liked is that how students get unique ways to cheat in every exam though most of them are highly unrealistic but even Hollywood movies are also sometimes unrealistic. It serves is purpose which is to make people laugh. Overall, i recommend everyone to watch it.
