Really, all awful people screwing eachother over, and in doing so screwing over themselves. Did they all somehow forget that they all need to pass, or it's like none of them passed? Morons.
No one said sabotaging others means they will fail the exam. The harvest festival is a way to show your skills so as long as you get a certain amount of points, you still can be promoted. It means you can sabotage others and they still can be promoted if they're good enough. This is not the Batra Party where only the winners get the prize.
This arc is really just reminding us that they are all devils in the end. Everyone is awful when they're not being influenced by Iruma. That's their whole thing!
Still, I wasn't expecting to hate Kerori quite so much. Good job, author.

Except time is running out, and so far they always stole all of the points. Unless they already turned in enough to get promoted, targetting classmates really screws yourself over. Unless you are absolutetely sure they already got promoted, targetting a classmate actually risks them failing. Which would fail you, since the entire class has to pass the bar.
@cor3zone
They heard the announcement so they know each others points now and since they all got a passing mark (Except for Iruma and Lied but they didn't know that until the announcement) so they can just go all out with their bet.
And Elizabeta&Clara stole Iruma&Lied points during the first day. They had three more to go and harvest.
