Drusilla feels this ought to be done properly. The Mid-Term Exam of Potions by their HoH!

However, she begins her Mid-Term Potions Exam with spilling most of her ink on the table. Luckily, the parchment stays stainless. She blushes slightly, glances quickly around to see if anybody noticed, and makes a rather complicated wand movement while muttering something. The ink slithers back into the bottle like a tiny little green snake.

She seems a little dizzy after the incident and cannot start answering right away.

The exam doesn´t seem to be very difficult, but you can never tell, and she´d just lost some precious minutes. However, everything seems to be simple until the last question. Why cannot I remember this, she thinks even though she´s sure she has heard about it. She tries to approach the problem logically, and writes something that makes sense to her after biting her silvery quill with concentration for several minutes. She frowns at the parchment reading it through before delivering it.
