Studentshare has a large database filled with students work. One gains access to this database by contributing. You start off with a free trial but after 10 minutes of use, you must create an account and upload a piece of work whether it be homework sheets, projects, essays, old tests, or notes. After an upload you receive 30 minutes of use, and for ever “like” you get on the upload you get 5 minutes, and every “dislike” you lose 5 minutes. Also for every comment you leave on others work, you receive one minute and if that comment receives a “like” you gain another minute, if it gets a “dislike” you lose a minute but be careful, you can only leave 10 comments an hour. If you don’t want to upload anything or leave any comments, you could always buy time.
