be handwritten.) You can put anything you want in these notebook(s), but here are
suggestions of things you might put there.
a. A copy of the homework and preassignments.
b. All of the equations from the lecture notes and textbook.
c. All of the definitions from the lecture notes.
d. Notes on topics that give you difficulties.
4. Get enough sleep the night before the exam.
Are you ready?
What do you need to bring to the exam? (You are not allowed to have
anything else at your desk!)
1. an HB lead or #2 pencil
2. a calculator
3. extra calculator batteries
4. your notebook(s)
5. a watch
6. a scantron
Rules for the exam
1. Do not enter the room until Dr. Mike says to come in.
2. Leave all backpacks and other material at the front of the room.
3. Do not talk unless Dr. Mike gives you permission. (You may raise your hand and
he will come over to answer your question.)
4. You may NOT have a cell phone or other communication or electronic device
with you during the exam. (If you leave a cell phone in your backpack, turn it off
or set it to mute.)
5. There will be directions, exams and scantrons at the front of the room, take only
one of each.
6. Sit in the seat with the same row and column number as the one written in red on
the top of your exam. (If you are confused, consult the exam directions that will
be given to you at that time or talk to Dr. Mike.)
7. Look at the directions to see rules for filling out the scantrons and begin filling
out the top.
8. Write your name on the exam and use the exam to do your scratch work.
9. Mark answers on the exam as well as the scantrons.
10. Watch the blackboard for further information during the exam. (What is written
there will be considered part of the exam.)
a. Be careful of the time. You will have only 50 minutes for the exam. It will
start promptly at 10:30am and end at 11:20am. (Dr. Mike will count down
the last 10 seconds. There will be no extensions without a letter from
Services for Students with Disabilities.)
