ClassDox is a marketplace for class notes. Students from all over the country are allowed to post these notes that they have taken and have them sold to the ones who had to be absent that particular day, or who were snoozing it out at the back of the classroom.
Notes are usually uploaded as PDF files, and they are categorized by school, teacher, class and the actual date that they were taken. In other words: the chances of you buying something that is not what you want are non-existent. You can look notes up based on all these different parameters at once. There is no room for misunderstandings here.
Plus, the site also lets you buy books using a supple interface. You just pick the title you need using a slider, and put the money down in order for the deal to be done. And when you are looking books up, you can see the notes that have already been uploaded for these. Double useful.
