High School...!

MFW my school has a video game club. YEP, JOINING THAT SHIZZ.

Mine has had one since before I went there, lol

Set a lunch routine ASAP. Cafeteria food could either be alright, or kill you emotionally.

One of the most important things right here. Unless if your school has enough funding to have its own meal plans, eating unhealthy food every day can really get you down. I personally suggest making your own (and knowing how to cook is a really good skill to have later in your life).

I have to disagree with Erik regarding in not taking all honors/AP classes, at least if your school is public. Honors classes typically have kids that are motivated and relatively intelligent: you want to be friends with these people.

As far as studying goes, don't be afraid to utilize sites like Khanacademy and Wikipedia if you're not grasping what you're being taught. It's important to realize that teachers are just people too: nine times out of ten, they're not teaching the concepts to you in an efficient way if you're not understanding something (this is also good prep for college, where it will be necessary to cross-reference information). On the contrary, as Altera said, it's important to make relationships with teachers who see potential in you: especially if they teach a subject you're interested in majoring in. If you do have ivy-leagues in mind, go to their websites and plan the courses/test preps you take to fit their admission requirements. Don't be intimidated by academics; the courses are created to improve you.

Socially, I think Darre and Altera covered it pretty well. The only thing I'd add is not to JOIN ALL THE CLUBS!. Seriously though, find one or two clubs that have things you like and are good at and make friends from there. Just be yourself and you'll meet like-minded people (granted, if you're not making friends, try being more of an extrovert). Stay away from obvious bad crowds and bullies, though I personally prefer the more agressive route of learning Judo.

You'll be great, Winnie - I know that you're very bright, so good grades shouldn't be a problem, and you're a very talented drawer which will be recognized by people. Don't be intimidated by people and don't get too wrapped up in social drama - it's as pointless as it seems.

MFW they only play sellout titles. Every damn time.

Actually I talked to the teacher a few days ago via e-mail:

I've been trying to get a TF2 LAN party together once we have enough players.
