ENGINEERING GRAPHICS TEST – REGIONAL
This Test Consists of 50 Questions
Engineering Graphics Test Production Team
Ryan Brown, Illinois State University – Author/Team Leader
Kevin Devine, Illinois State University – Author
Jacob Borgerson, PhD, University of Illinois at Urbana-Champaign – Reviewer
Mary Weaver, 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.
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 incorrect answers.
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 seem too difficult for you. Go on to the other questions, and
then come back to the difficult ones later if time remains.
*** Time: 40 Minutes ***
DO NOT OPEN TEST BOOKLET UNTIL YOU ARE TOLD TO DO SO!
