Notice how the books fit well sideways on one side; folders and notebooks fit on the other side.
If you organize your desk this way, you should have room at the front for your dictionary and a small pencil pouch (in the photo the pouch is hard to see because it's tucked away, but it's pink).
NO papers should be loose in your desk; always keep papers in folders.
Don't keep more than two extra books, pencil boxes, or binders in your desk. If it gets too full, it won't shut and it will be hard to find things. You are allowed to keep your binder under your chair (but nothing else).
