A three-ring binder allows you to insert and take out specific pages for review. Further you can keep notes, handouts, and returned work in chronological order to allow for easier access in preparation for tests. Binder pockets and folders also facilitate keeping your binder in order. Ideally, you should develop a system where by you have a Black Day binder and an Orange Day binder. Since you will be taking anywhere from 6-8 courses, you may wish to transfer those Black Day notes into appropriate binders at home during your daily review and revision of your Cornell Notes.
