My school had the A day B day system, so four periods were on an A day, and the other four were on a B day. The only disadvantage was that you only have classes two-three times a week. I think the pros outweigh that though. Having class be 1.5 hours long allowed for you to absorb much more information. And for those complaining about music: move to Oregon. We put a lot of emphasis on music programs, and our state competition is probably one of the highest levels in the nation (so says the out of state judges we had)
School is alright. College for me is much easier than High School. I write a paper in high school and it gets a C+, but at ASU I get an A+.
