Query: A fast, enjoyable, memorable read

I have not read this book in a very long time, but I remember it as being a favorite from the first time that I picked it up at the age of 12 or so.The book is about a group of students in a survival class who get stranded on the planet where they were supposed to be living for only a few weeks as a test. The way their group evolves into a little society was very interesting (and not nearly as dark as what happens in a similar situation in The Lord of Flies). I don't remember very many details, but do remember being completely enthralled. Recommended.
