Quizzes- Home-Works

There are nine quizzes in addition to the three exams. Quizzes, however, are in reality just home-works! That is, in the content for each chapter, I have provided you with the “quiz” problem(s). After seeing the quiz problem, you can print the problem(s) and work to find the solution. Once you have the solution, you can go to the “Quizzes” icon on the homepage and take your quiz by the deadline. Therefore, quizzes are simply computer-graded home-works. I have prepared them in this manner to create flexibility for you.

Remember the quiz problems will HELP you to figure out the answer to the quizzes. These problems and quizzes, in turn, will help you to do well on the exams. Also, remember that you have limited time and TWO chances to take a quiz. However, you have plenty of time to figure out the answer to the quiz problems before you actually take a quiz. You will be wise to take the relevant quizzes BEFORE each exam, but you have time until the last week of classes (before the final week) to take all of quizzes. Make sure to take them all BEFORE the deadline.

A Tentative Timetable For The Coverage Of Course Material

Please pay close attention to the DATES of exams and CHAPTERS over which you will be tested, WEEKS are less important. Also, slight adjustments are possible. The professor reserves the right to vary the class schedule, depending on student response, the need for increased / decreased time for coverage of topics, and possibly important events / speakers.

Examination and Grading Policy

Distance learning students will take their tests and quizzes online.
In-class students will take their quizzes online but their tests in-class.

Exam 1	25%
Exam 2	25%
Final Exam	35%
Excel Data Analysis Exercises	7%
Homework Assignments & Quizzes	8%

The following guidelines will be used to determine letter grades:

A = 90% - 100%
B = 80% - 89%
C = 70% - 79%
D = 60% - 69%
F = Less than 60%

Attendance, Extra Credit Work and Other Course Policies

No “official” attendance will be taken. However, extra credit work as well as in-class Excel Data Analysis Exercises is offered in-class. Naturally, only those students in attendance will have the opportunity to earn these points. Distance learning students must check the course web site at least once a week to make sure they are up-to-date on all e-mails sent by Dr. Samavati informing them on the extra credit opportunities, Excel data analysis exercises, and other information related to the course.

Additional Information

1. In-class students are allowed to bring a one-page “formula-sheet” to each test. The purpose of this formula sheet is to help alleviate the need for memorizing long computational forms of the formulas. Therefore, the intent is not for the students to use a summary study sheet, where the students have written a summary of all the information. The sheet must contain formulas ONLY.

2. Dates of quizzes- home works are posted on the course web site. You can see them by clicking on each quiz. Make sure to check all the deadlines so you do not miss your quizzes and assignments.

3. Excel Data Analysis Exercises – In-class students will complete these exercises in class. Distance learning students are given deadlines and will submit their work online.

4. If you are ill and cannot attend an exam, you must notify me before the exam. Those who miss an exam without notification will receive an "F" for the exam.

5. DISABILITIES STATEMENT: If you have a disability and need assistance, special arrangements can be made to accommodate most needs. Contact the Director of Services for Students with Disabilities (Walb, room 113, telephone number 481-6658) as soon as possible to work out the details. Once the Director has provided you with a letter attesting to your needs for modification, bring the letter to me. For more information, please visit the web site for SSD at http://www.ipfw.edu/ssd/
