Test Information
Instructions
Description This assignment is made up of 25 questions with a mix of multiple-choice and
true/false. It is based on the content of chapter 0 in our course textbook. It will be
available for an extended period of time for this particular assignment due to the
problem with textbooks not currently being available in the campus bookstore.
We have contacted the publisher and have been promised that textbooks will be
arriving on campus on September 20th (this coming week). As a result of this, we
are extending the deadline for completing this assignment until September 30th in
order to give all students at least 10 days from when textbooks will be available
until the assignment deadline. This assignment will be available from
Saturday, September 17th until Friday, September 30th, at 7:00 pm at which
time all submissions of the assignment must be in for grading. Anything
submitted after 5 PM on September 30th will be late and not marked or included
in the calculation of the overall assignment grade for the course. It is
recommended that you also look over the lecture slides for chapter 0 (from both
professors) as they may provide an easier route to finding answers for many of the
questions. As per our stated policy, students will be given two opportunities to
submit their answers to the assignment. For each attempt, an overall grade on the
assignment will be available through the MY GRADES folder on Blackboard, but
the correct answers to the assignment questions will be posted several days after
the deadline for submissions. Good luck!
