She is among the top 20

When Mrs. Miller walked into Evergreen Class holding exam papers, her lips tightly pursed and wrinkles on both sides of her mouth were visible.

Evergreen Class could feel the brewing storm, as if she was on the verge of erupting.

They were relieved when they heard her first sentence,

"The overall performance of our class this time is acceptable, there's not much difference with before."

But in the next second, she slammed the exam papers onto the lectern!

"But your performance in math is so poor!"

"There's not even one full score in math!"

"Out of three full scores in total, even the International Class upstairs has one, why doesn't our class have any?!"

"Did I teach worse than the math teachers of the other two classes?!"

Mrs. Miller was frustrated.
