Please note:
Midterm exam is a piece of academic task for this class. It provides an opportunity for students to learn, practice and demonstrate they have achieved their learning goals. It provides evidence for the teacher that the students have achieved their goals.
This is an important exam with a 20% overall grade! You are not allowed to receive help from anyone to complete this assignment. Also, you are not allowed to directly copy and paste your answers from any other source including from the Internet as that is a violation of the school policy and is considered cheating and will result in receiving a grade of zero for the assignment.
Instructions:
· Midterm covers Lectures 1 to 5 and documents posted on Moodle.
· You must work on this file! Please return this file to me via Moodle as soon as you it. (don’t convert to pdf or another format).
· Add your name on the top of this page and rename this file as INST560Mid_ yourname, then submit it on Moodle ( Important: you will lose 5 points if you do not follow the rules).
· If you think a question is unclear, mark what you think is the best answer. As always, I will consider written regrade requests if your interpretation of a question differs from what I intended.
