Claim:   Student makes humorous guesses at answers on chemistry exam.


Origins:  On our "Shortchanging the Subject" page we cite some legendary examples from students who, faced with essay exam questions they couldn't handle, chose to answer completely different questions


The images linked below illustrate a different approach to handling unanswerable test questions: just write anything, even if your responses are completely goofy and nonsensical. You may not get any credit for your answers, but at least you'll have the satisfaction of knowing that you didn't leave sections of your exam paper completely blank. There's always a chance the professor may not read what you've written, or that he'll be sufficiently impressed with your honesty and sense of humor to throw a few points your way.

Even if the student whose 2003 chemistry exam is excerpted below didn't score any points with his professor on these selected questions, his answers are worthy of enshrinement in this collection of contemporary lore. Each of the pages shown here will display a full-size image when clicked upon, and the questions and answers given within each are transcribed beneath.
