Throw them away, which means put them in the recycle bin. You use notebooks for class, you don't seem to ever fill a notebook used for a class, you've ripped out the used pages (think carefully about whether you need to keep all that used paper). What do you use notebooks for now? If for a journal, get one journal notebook. If for notes on various topics get a loose-leaf notebook where you can add or delete pages as needed. You can use those thick pages with labels to organize topics withing the loose-leaf notebook.

I've been where you are; letting go of written material is hard enough. Keeping unused paper 'in case' is a false economy. You'll waste more time and energy moving it around, and trying to decide which partly used notebook to use, and making space for the box ----it's all too much. Toss them.
