1 LECTURE 15: MIDTERM REVIEW IMA 101 Basic Mathematics 7/29/ IMA101 Basic Mathematics

2 Midterm Information Time and Location:  Tuesday August 3, 2010  15:30 – 17:30  PC 401 7/29/ IMA101 Basic Mathematics

3 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

4 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

5 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

6 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

7 Cheating Please do not cheat 7/29/ IMA101 Basic Mathematics

8 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

9 Midterm format 10 questions Similar to what you have seen on the homework  Some word problems, some calculation, some conceptual Divided equally among the topics  20% of the midterm from each week  10% from each lecture (lecture 2 included with lecture 3) Note: some questions might combine topics 7/29/ IMA101 Basic Mathematics
