Hermione Granger studied her butt off. The first test of the year was coming up, A cure for boils potion she needed for Potions with Snape, who gave you F's when you could have gotten a A if you had a different teacher. She FINALLY finished reading hundreds of books about Potions. She was just going to rest her eyes when she woke up on the couch in the Griffindor common room. Oh no! It was 8:30. Potions started 30 minutes ago! Hermione finally got to class. Professor Snape sneered at her "Granger did you know you just cost Griffindor 20 points for being late?" Snape snapped at Hermione.
"I'm sorry, sir. I stayed up late last night studying.", Hermione replied. She took her seat and made the potion. As she was distracted, Draco Malfoy slipped centaurs butts in her potion. All of a sudden, Snape gave her a grade. "Granger, you got a B. Why did you add centaurs behinds into it? For a silly joke you Potter and Weasley played?" Snape sneered.
Hermione was mortified. She only got A's. She never got a B in her life!
