Grammar en Español
I've been reviewing my Spanish over the last couple of days using my Side-by-Side Spanish & English Grammar book. I edited the notes I took, and realized how little I had decided to keep from what I had scribbled down. That's a good thing though, because that means I remembered a lot.
I'm not obsessed with grammar, but since I primarily concentrate on reading and writing, it's kind of hard not to have a certain amount of focus on it.
