The site has attracted some controversy with teachers accusing it of being a tool for cheats. Apparently students will use it instead of reading the actual book. I can’t believe it! It can even be used to cheat during tests using mobile phones with Internet access. I can still remember a friend of mine getting an A for an essay about Oliver Twist based on the Lionel Bart musical.
