  1. IMA 101 Basic Mathematics Lecture 15: Midterm Review IMA101 Basic Mathematics

  2. Midterm Information • Time and Location: • Tuesday August 3, 2010 • 15:30 – 17:30 • PC 401 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 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 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 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 IMA101 Basic Mathematics

  7. Cheating Please do not cheat 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 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 IMA101 Basic Mathematics
