Class B English classes must be fun.
They're taking a test, and it's completely silent apart from Tetsutetsu constantly whispering: "Pony... hey... psst... what's the answer to question 6?" And he gets on her NERVES so Tsunotori is totally ignoring him.
Mic can't hear him, he's got his back turned and he's deaf as a post. Honenuki asks him to lay off, but this only encourages Tetsutetsu to bother him instead. He might not be a native speaker but he's still pretty damn good.
By now, half the class' eyes are on Tetsutetsu. Kodai is giving him this look that puts the fear of God into him. The silent ones are always the scariest. Shishida keeps grumbling in annoyance. Awase is trying to prevent Monoma from getting involved (he honestly can't tell if Monoma plans to berate or help Tetsutetsu).
Kendou, who's been bashing her head off the desk for the last 30 seconds, is too far away from the troublemakers in Mic's classroom, so Tokage steps in, clipping Monoma and Tetsutetsu over the back of the head. It doesn't knock them out, but it stops all the chaos.
Tetsutetsu does not pass that test.
