                                               IMPORTANT  

·   Student will be qualified to take the final exam if his/her total is at least 20 over 66, by the last day of the classes.

·   Students who do not have least total score of 20 over 66 will be given an FZ grade.

·  Students who have missed a midterm exam and have valid, well-documented excuse can take a makeup of it. A single makeup exam will be given few days after the second midterm exam.

·    Reserved 4-th hour will be used in some weeks, this will be announced in the class.

§    Usage of a statistical software such as MINITAB  is encouraged.

· This course is not a regular math course! It involves qualitative thinking and more words than other mathematics courses. 

§   Following and understanding the lectures is necessary but not sufficient for understanding the material. The best way for that is to do more problems, especially "supplementary exercises" from the textbook.
