From what I remember of high school it was a really fun time. Sure there was plenty of suck involved, but overall it's a lot of fun. Now, I've been out of high school for a while and honestly only stay in contact with a few people, but my high school was a terrible, terrible place. It still was a lot of fun.
Things to keep in mind
More people mean more girls. The only draw back here is it might be even harder to concentrate and get your work done considering how high school girls dress these days. When I was in high school it was all big baggy sweatshirts and baggy jeans.
If you do something stupid or embarrassing, don't sweat it. Someone will do something even stupider or more embarrassing tomorrow, if not sooner.
Take all the elective classes you need to graduate in your first two years. I know we had to take like 2 years of a foreign language, sociology, and some other junk. Knock those out so in your junior and senior year you can take blow off classes and study halls. This will leave you more time to get your homework done in school so you can go out and do other stuff after school (or get a job which you'll need if you date a lot).
Try to line it up so you take drivers ed and will be ready to get your license as soon as you turn 16.
Get into trouble. Nothing too bad, but c'mon. You're only young once.
Enjoy Highschool while you still can, because you'll miss it once you go to college.
Dude, enjoy College while you can! College was AWESOME.
Oh and no one is going to take the beat down to you. Contrary to what's portrayed on tv, no one stuffs people into trashcans or lockers anymore. You shouldn't have any worries.
We did. I had it done to me and did it to plenty of people. It's just high school though, not really a big deal. If anything like this does happen, just take it with a grain of salt.
