What To Keep In Your Backpack

• Textbooks, binders, obvious stuff. Make sure to use your locker, and I'm sure that you have time during the day where you can go and switch out books as necessary
• Pencil pouch containing: 2 different colored highlighters (make sure one of them is the classic neon yellow), a mechanical pencil, a No. 2 pencil (for Scantron tests), mechanical pencil led (make sure it's the size that the mechanical pencil takes. i.e.: 0.5, 0.7, etc.), 2 black pens, a flash drive, colored pencils (12-24 pack), calculator (specific for whatever math/science classes you take), a good eraser, and a red correcting pen.
• Cell phone
• Earphones 
• A small key pouch/coin purse/wallet (whatever you would like) with: your student ID, a little cash, and your driver's license/permit (if you're old enough)
• House keys (if necessary)
• Mint gum
• Hand sanitizer (if you get one from Bath & Body Works, you can buy a cheap holder that you can attach to your backpack
• Makeup bag containing: drugstore concealer (you don't want an expensive one to get lost), oil blotting sheets, moisturizing lip balm, lip gloss (go for a softer pinky-nude, or whatever works with your skin tone. NYX has some really nice glosses for a pretty inexpensive price), travel pack of makeup remover wipes, travel size perfume (glass bottles aren't the best), black mascara, hair ties in a basic color (black, brown, etc.), bobby pins, and a black pencil eyeliner.
