Meanwhile, Marli is becoming the teachers' and the public's pet! She was given an A which means she'll have a special treat later in the week.
And she gets to choose who she wants to sing with on Friday.
The public will vote for one person who they think deserves to stay. Then the other students will decide who is expelled.
