INST Certification June 25 2008 Version02 PDF
This is a multiple-choice exam. Books and hand-written notes are allowed, as well as a scientific calculator.
However, you may not reference old exams, course assignments, or other printed materials.
You are to choose the best answer for each question. This means there may be more than one answer which
could be considered correct, but there will definitely be one answer that is better than all others.
It is strongly recommended that you do not change an answer unless you are absolutely sure it needs to be
changed. If you feel unsure, leave your initial answer, because it is probably right.
A wrong answer counts the same as an unanswered question, so it pays to guess if you do not know the
answer to a question.
This exam is an overview of concepts spanning the entire two-year stretch of the Instrumentation and Control
Technology program. Unless you are just finishing the final quarter of this program, you will no doubt find
some sections of the exam unfamiliar. Do not be concerned about this simply do your best to answer all
the questions.
The second page of this exam is a bubble-type answer sheet. When the exam time begins, you are to detach
this sheet from the rest of the exam, write your name on this sheet, and also mark the quarters you have
studied (F, W, S ; Fall, Winter, and Spring) in the Instrumentation and Control Technology program.
