Ahaha, it's not really that chaotic, not normally anyways. This year, everything has been so chaotic because of everyone changing their schedules & whatnot. My school screwed everything up this year. D; Thankfully, my schedule doesn't really need to be changed.
It's block scheduling; basically, what it is, we have 3-4 classes on one day and 3-4 classes on the other day. (I say 3-4 because it depends on how many classes you're taking where I live.) It alternates between A and B days, and if the week ends on an A day, you continue on a B day and vice versa.
That's always fun. I had history 1st block on my A days freshman year; sophomore year it was 4th block on B days. This year, it's 2nd block on A days. :3 I start off with Spanish 4 on A days & Probability & Statistics on B days.
Haha, nice. This one girl who rides the bus with me asked me what I was and I was like "Soph-- uh, junior." It feels like just yesterday I was a sophomore too. D;
