Utensils
Every class you take will need writing utensils, but what kinds? As a general rule, you should try to have at least one pencil, mechanical or not, a red pen, a black pen, and at least one highlighter.
Binders
For more complicated classes, some teachers will tell you that you need a binder. This is not required, but can be very useful for keeping things in order by dates or units. Binders are most helpful in science and history classes. Don’t have too many binders because they can overload you with lack of space and too much weight in your bag.
Notebook
It’s a good idea to keep at least one notebook in your backpack, even to just use for loose-leaf paper. It’s also a good idea to have one for classes that require you to take a lot of notes.
Calculator
A calculator isn’t just helpful for math classes. You’re also going to need one in any STEM classes you decide to take, and it’s a worthwhile investment to go ahead and buy a nice graphing calculator, though it’s not a necessity. Most math classes will provide calculators if they are needed, but if you’re doing stuff like homework outside of class, having a calculator will make your life less difficult.
Folders
To keep your papers organized and un-crumpled, having some folders can really help. Color coordinate them with the classes they’re for or get a file folder for maximum space efficiency.
Planners
t least trying to keep track of assignments, you are wrong. Only some classes have assignments listed on canvas, so you can’t rely on its to-do list to make your way through school. Especially in honors and AP classes, every assignment counts. Having a planner lets you keep track of both short-term and long-term assignments, even if it’s just on your phone.
Extra Supplies
Keep extras! If you are using a mechanical pencil, keep extra lead and a big eraser on you. If you use your pen a lot, stick an extra in your bag in case you lose it. If you only have the bare minimum, what are you going to do when the bare minimum runs out? Even if you keep them at home, it’s a good idea to have extras.
