Assassination Classroom Season 2 Episode 12

The episode  starts off with Nagisa telling us about the hardest math problem on the exam. He says half of the grade didn't make it that far, and the other half made it in a nick of time. It ended up being that the only people able to get full marks on that problem would be Karma and Asano.

Karma remembers how Nagisa always talked about talent. He reflects in everybody's talent. Asano is the first to start the problem. Karma is looking like he might fail, but all of a sudden realizes how he is going to solve the problem. He ends up solving the equation telling us how to do it, but it's still confusing. Asano didn't get to finish the problem.

Everybody made it in the top 50! Asano's father I'd scarier than ever! What happens when Asano's father hits him hard enough to send him spiralling across the classroom?
What happens when he destroys class E's  campus? When he fires Koro-Sensei?
