Well, my personal essentials are...:

• My iPod: I'm a music whoooore!
• Pens: I only ever write with black pens, so I have two in my bag
• My wallet: My new school is about a minute away from the mall, so I'll definitely be needing my wallet this year xD
• A novel: I alwaysalwaysalways carry a novel or something I can read when I get bored with me to school, seeing as I tend to catch the bus home.
• Makeup: Ugh, call me what you will, but I hate not wearing makeup. To be noticed here by any guys, you have to have perfect makeup even if they're super fugly
• Fruit: I don't care about having a proper lunch. Just give me a bag of grapes and some mandarins and I'll be happy
• A bottle of water: You've got to stay hydrated!
• A little notepad: Just for all the little bits and bobs that pop into my head when I'm bored in class
• Body spray and deodorant: Total necessities! B.O. is just...ew.
• Tweezers: Splinters, eyebrows, whatever. I don't care, just don't let me leave without tweezers.
• Feminine whatnots: Don't get me started...

Then there's the list of things I kind of need when I'm at school...:

• Exercise books: One for each subject. I despise 5 subject books.
• Textbooks: I'm taking psychology, continuing Japanese and a few other subjects that require me to lug around HUGE textbooks this year...I'm excited :D
• I.D.: It's just a requirement that we carry our school I.D's around with us so people actually know we attend the school.
• Calculator: When I have maths, at least...

About 10 books
Hairties
Black sharpie
Phone
Cash
Chapstick
Ricola/ Halls
Sketch paper
Laptop

This could be for any bag, but I usually have most of these when I go to class:

-At least one of each: pencil,pen-black or blue, pen-other color, eraser
-Lip balm
-Notebook(s)
-Phone
-Wallet
-zune
-Body Spray and/or Deoderant
-Emergency mother nature kit =D

I keep all my text books in my locker so they aren't in my bag

I tend to put mine in my locker, but sometimes it's just easier for me to carry them with me all the time, otherwise I run out of time to go to my locker.

pfft. We don't have lockers here. It's lame.

I take...
* 4 Books.
* How ever many text books I need that day
* 2 pens, and a calculator shoved at the bottom of my bag somewhere
* Wallet
* Deodorant
* Lunch when I can be bothered...
* A lighter, and a couple other things.
* Ipod

and what? you don't put condoms in a bag! god.
My phone of course, but I don't put that in my bag cause it would probably get stolen.

Just remembered more stuff I carry around...

-Money (in case I need to buy lunch, take bus, etc...)
-Book (I get bored, and registration on Fridays is reading time)
-Blank notebook (in case I forget certain exercise books/need to write something down/whatever)
-Random exercise books
-Textbooks
-Homework diary/planner/whatever you want to call it (has my timetable, homework assignments, end-of-term dates... basically, I cannot live for a single day without it)
-The petition to get the cafeteria 'seating plan' changed back to how it was (not actually mine, but for some reason my supposed 'friend' is incapable of carrying it in her bag)
-Trainers, shorts, PE top (only on PE days, usually in a plastic bag)
-French dictionary (only on French days)
-Probably a load of overdue homework sheets that have been completed (or not, as the case may be)
