I'll try and give my honest opinion. To me this drama is like a hard core version of a real life high school experience. At least to me it didn't happen exactly like in this drama, but there were ranking, bullying, bad teachers, and etc. I would say that this drama is something that you could to learn from. If you're in that situation or know someone that is. They could see how Baba-san solved her classmates problems and her own and eventually you could use this to graduate safely.
