Muggle Studies. She was not very surprised when they were not allowed to use magic.
Plus, they were going to use notebooks, pens and pencils. That was a very exciting start for a lesson.
Beatrice knew about these things because even if she was half-blood, her parents made sure she was not alien to the Muggle and Wizard world and that is why she respects the existence of two world so much.

Now aside from Magic, what else was different from the two worlds ?
"Well Professor, aside from those already mentioned, there are the Animals. Muggle Animals differ from Magical creatures in their lack of magic, appearance, features and even knowledge. A number of magical creatures are combinations of animals in found in the muggle world." she said, thinking about her Siberian cat, Davinci.

Beatrice got a little jealous with the other students eating some goodies so she decided to get some for herself. Oh, toblerones are heaven. And was there no ice creams ?

She slowly made her way back to her bean bag when she heard that some of the students are now starting to talk about racial discrimination. Or, was it comparison between muggles and wizards ? She couldn't help but give her opinion about this. Insults were highly prohibited in this class. "Hey." she called out to those chatting about muggles, how silly they are and things like that, "Not just because you're a pureblood means you could go on using foul words for muggles. They too have their right to be respected as much as you so you better start practicing that respect if you want to gain the same." And she trotted back to her bean bag. Munching on her toblerone.
