5. Not taking the Arithmancy book because we have more important skills to learn and focus on, and this one is one we can learn the hard way in class. (there's also likely some books on it in the course books)
6. Not taking the Care of Magical Creatures since we won't really be caring for magical creatures, not taking Divination quite yet as I'd prefer to focus on other things, not taking the books on wizarding culture and law as they aren't likely skill books, and not taking Hogwarts, A History as Hermione has a copy and it's not likely a skill book. Fuck the Harry Potter series and fuck Lockheart.
In regards to Arithmancy, Divination, Care of Magical Creatures, etc. they might still come in handy. If nothing else, they might allow us to grind skills or stats we otherwise wouldn't be able to, or if they are skills, might save us time since we don't have to acquire it the hard way.
In regards to wizarding law and culture, I figure it can't hurt to get more familiar with the "law" part in particular; see if brushing up our knowledge in that regard can prevent us from being jerked around later.
