What to expect in a high school?

One of the cool things about high school, in my experience, was that -- just because there were more people than in middle school -- I was no longer an isolated weirdo, but instead I could hang out with other weirdos. Also, many people seemed to have magically matured over the summer. Aside from the workload (which was worse), on the whole I'd say it was much more fun than my previous school years.
