Isla just smiled when the professor complimented her answer. But when she responded to Kaiser's answer with something that was way over Isla's head, the first year just stared in disbelief. Ummm, yeah. Whatever that stuff meant...

Thank Merlin the lesson didn't require them to do any calculations about the size of the sun. Apparently they had to know what was discussed the first two years before this one, though. If this lesson was any indication, Isla was doomed. Wasn't Astronomy optional?

At least muggle school science had somewhat helped her know a little about the next question, so she raised her hand. "Sometimes it can cause us to see a lot of the moon, and sometimes it can cause us to see none at all," she said. She wasn't even sure if this was right. She just remembered something like this being talked about in class.
