So, I don't know about you, but I tend to be pretty unorganized when it comes to school. I found some nice tips and decided to post them.
1)
In your locker (or wherever you put your things), keep everything for one class together. I keep all of my math stuff next to each other, all of my science stuff next to each other, and so on. This just helps with putting stuff in and out of your storage space quicker.
2)
If you have a school planner, USE IT! It may seem like a waste of time, but it helps when you or a friend can't remember your assignments. If you don't have a planner, a notebook would work just as well.
3)
Always plan ahead with your assignments. If you have after school activities the day before a project is due, finish the project before then so that you don't have to stay up super late finishing it.
4)
Always carry a binder around with you to every class. You can keep worksheets, your planner/notebook, extra paper, and class schedules in here. 5-10 dollars well spent.
5)
Carry a pencil case with you to every class, also. Keep your pencils/pens, calculator, erasers, and any other things you find necessary.
6)
Write your name on everything. Don't wrote it on pencils or pens, that's practically pointless. Just the main stuff-notebooks, binders, pencil cases, calculator, planners, etcetera. If you drop something, you can easily find it and prove that it's yours.
Hope these tips worked!
