If you’ve recently been a student, or you have a child or grandchild that has, you may have some untapped gold at your fingertips. Those old revision notes weren’t just useful for passing your exams, they can also be used to generate extra cash.
Upload your notes along with your asking price to sites such as Notesale, to get paid by other students following in your footsteps. Not a fortune maker, but why not cash in on what you already own but no longer need?
