• I have assembled here 25 of the hardest questions that I know.  All of which are designed to make you think.  The only requirements for this test are basic math and physics knowledge as well as good observation and reasoning skills.  You'll probably get most questions wrong if you try to do the test quickly. Many people will get many answers wrong anyway.  But maybe you'll be one to get all the answers right and achieve the ultimate prize.  Be sure to read the entire test before you answer the questions.  Good Luck!
