Don Wayman, WYSE – Coordinator of Test Production GENERAL DIRECTIONS Please read the following instructions carefully. This is a timed test; any instructions from the test supervisor should be followed promptly. The test supervisor will give instructions for filling in any necessary information on the answer sheet. Some Academic Challenge test sites are using answer sheets that require you to fill in the letter of the answer you choose on the blank line after each question number. Others may ask you to indicate your answer to each question by marking an oval that corresponds to the correct answer for that question. Only one oval should be marked to answer each question. Multiple ovals will automatically be graded as an incorrect answer. Be sure ovals are marked as . Not as , , , etc. Test Question - 1. Which planet was closer to Earth in 2003 than it had been for 60,000 years? a. Jupiter b. Mercury c. Neptune d. Mars e. Venus Answer Sheet-- 1. If you wish to change an answer, erase your first mark completely before marking your new choice. You are advised to use your time effectively and to work as rapidly as you can without losing accuracy. Do not waste your time on questions that are too difficult for you. Go on to the other questions and come back to the difficult ones later if you can.
