On this episode, the students take the term's final exams. Later, they get the results.
So I'm not too fond on the imaginary action of the students as gladiators fighting against exam questions as monsters but they fortunately didn't make that scene too long. Although the end results was pretty cool to watch. Other than that, Koro-sensei was dealing with the situation nicely. Now what's going to be a new threat for the E Class? Overall, a nice term exam plot ending.
Conclusion: A nice term exam plot ending.
