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. Most
Academic Challenge sites will 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.
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 have time.
*** TIME: 40 MINUTES ***
