I use refill pages, cause I don't usually make summaries (which I type up) as soon as we finished learning that dot point, and I like keeping related information together. If I wrote in a book and kept everything in date sequence, info on that dot point would be all over the place. 1 folder for school, 1 folder for each subject at home, 1 folder for summaries. And I don't lose sheets cause I hole punch/stick reinforcer stickers on sheets as soon as I get them so they don't rip every time I flick through folders.
People at school seem to be easily amazed by those stickers.
