Arithmancy, Etc.

Several listees have posted comments about Arithmancy 
being "divination by numbers" or similar to numerology (sorry, lost 
track of individual names).

I'd just like to add that the title of Hermione's textbook (from PoA) 
is _Numerology and Grammatica_.
I've always wondered about the Grammatica part. I think that it has 
something to do with writing (language) and rules, but don't know 
what the non-Muggle meaning could be. Any thoughts?

Also, I wonder if anyone has tried to figure out the number and names 
of classes offered at Hogwarts. We know that both Percy and Barty Jr. 
have managed to get 12 OWLs, but when I tried to sum up the total 
number of classes  I also came up with 12 (Transfiguration, Charms, 
Arithmancy, Ancient Runes, Care for Magical Creatures, Potions, 
Astronomy, History of Magic, Muggle Studies, Herbology, DAAD, 
Divination). The only person who was taking all these at the same 
time was Hermione but she dropped two. That means there must be other 
classes that we know nothing about. Another possible is Flying 
Lessons, but I am curios to see if anyone has other suggestions.
