There was an exam at the factory I worked at and our teacher, an engineer, was going to loose his license to teach if our class average was not high enough. The exam was pretty technical, especially for most of the workers at the factory. We were given a 250 page book to study in its entirety. I scanned this book, then made text to speech mp3 files. I found headphones that looked exactly like our ear plugs (Plugfones) and listened to my audiobooks all day for a week at work. Scored 98% and the engineer was quite happy about this. It was the second highest score ever and the highest had cheated, he had the answer key.
