For anyone who remembers the dreaded exams, for those who teach, mark or enjoy a laugh, or for scientists wishing to take a look at the scientific world in a different light, then this is the book for you. Over the last ten or so years, I have been collecting "student bloopers" - all of them true and genuine, some of which you would not believe, others which make little sense, even to the trained eye! They come from a variety of exam boards, papers and levels but there are some, even now after reading them many times, which never fail to bring a smile to my face. Whilst this may be a humorous book, I believe it can genuinely be used as a teaching tool for the many misconceptions that occur in students' minds and, if that helps one person, then it has done a good job. Read and enjoy.
