School Tips

Some of my personal tips for you to get through high school.

Supplies

Buy a 2GB flash drive, specifically for school. You'll be doing projects over the computer, and having an extra flash drive will come in handy.
Have crayons/colored pencils in your bag. You'll get bored, and they do become useful :).
Have a calculator with you, unless your math class doesn't allow them. It will definitely help you, even in classes other than math.
If needed, get a locker shelf. It organizes helps you your stuff better, and you'll get comments on your neatness (I have experience).
Bring a separate school bag - you'll have a lot of things to carry around with you. Plus, if you forget it or its stolen, not much would be lost.
Carry an agenda book with you, it really helps to organize your homework.
With mass projects, make a checklist. That way, you'll see you're progress and will be more encouraged.
Have extra socks in your P.E. locker! It'll help.
Have a different colour for each subject. Ex., blue for math, red for English, etc. You'll recognize the colours more easily and it'll help speed up your locker visit.
If your school has bad clocks, bring a watch with you. You don't need to wear it, but having it is always nice.

Classes

If accepted into AP/advanced classes, take it!
Use lunch for studying/homework/things you want to take care of. I use my lunch to do homework and study Dutch.
If you'd like to be an artist or a musician, take art or musical classes. Because, if you wait 'til college, you might be too late.
Don't switch classes because you don't like your classmates.
Study, even if it's just review. It'll help you perform better on tests, and that could help your grade a lot.
Keep count of how many days you miss in each class, and use it!
Knock out required classes you don't like before going for electives you do like.
Don't step down classes, step up! At least try the harder class.
Learn the shortest/less crowded routes to each class. Learn how to actually walk!
Sign up for classes that you're interested in for a career first. Learn other stuff in your own time.
