LECTURE 15: MIDTERM REVIEW IMA 101 Basic Mathematics 7/29/ IMA101 Basic Mathematics
Midterm Information Time and Location: Tuesday August 3, 2010 15:30 – 17:30 PC 401 7/29/ IMA101 Basic Mathematics
Things you may bring to the midterm: Yourself A pencil and eraser A pen (blue/black ink only) One extra pen or pencil ONE A4 sheet with whatever notes you want to put on it (front and back) A wrist watch without calculator capabilities A clear plastic bottle of water English language dictionary 7/29/ IMA101 Basic Mathematics
Things you may not bring to the midterm: You are not allowed to use a calculator the questions will be designed so that it will not be necessary You are not allowed to use your cell phone Please bring a wristwatch if you need to check the time Food or drink (aside from water) The midterm is 2 hours long, please wait until the end of the midterm to eat or drink Notes or books aside from one A4 sheet of paper or a dictionary 7/29/ IMA101 Basic Mathematics
Cheating What is considered cheating? Cheating is: Communicating with another student during the time of the exam Using any external resources aside from the permitted single sheet of A4 notes Looking at or attempting to use another student’s work Behaving in a disruptive manner during the exam period 7/29/ IMA101 Basic Mathematics
Cheating Why do people cheat? Don’t study enough Insecurity Fall behind on the material Worried about not getting a good grade What happens if you cheat? You will be caught You will be expelled from the exam room and not permitted to complete the exam See handbook (read in class) You will lose my respect 7/29/ IMA101 Basic Mathematics
Cheating Please do not cheat 7/29/ IMA101 Basic Mathematics
Midterm Overview Questions are based on homework, lectures, and assigned reading Today: topics overview Tomorrow 2pm: question/answer session Graded assignments will be returned during the Q/A 7/29/ IMA101 Basic Mathematics
