There will be two homework assignments due each week. In addition to the webwork problems which will be submitted, I will post a list of related problems from the book. Although I won't collect these suggested problems, you are responsible for knowing how to do them. They are the types of problems that will appear in quizzes and exams.

I will post the reading assignments under the homework section. Reading assignments are actual assignments! You could be quizzed on a reading assignment, even if we haven't covered that section in class yet!

Quizzes and in-class assignments

I will have semi-random quizzes and in-class assignments (collaborative quizzes) . They are graded and should be taken seriously as assignments, but their main purpose is to prepare you for the exams. It is helpful to have practice working exam-style problems in a classroom environment. They will also give you insight to your strengths and weaknesses with the material.

If you miss class, you are responsible for the material covered in your absence. This means if you miss a quiz, then you are responsible for the 0 score you will receive on that quiz. If you know ahead of time you miss class, or if you have a medical or personal emergency and cannot attend class, it is your responsibility to contact me about making up the material you missed.

Exams

There will be two midterm exams and one final exam. The midterm exams will be 1-hour each, and the final exam will be a 2-hour cumulative exam. The dates of the exams are:

• Midterm 1: Wednesday, July 8
• Midterm 2: Friday, July 24
• Final: Friday, July 31

You must be here for the exams-I will not give any make up exams, period. If you have a documented medical or personal emergency I will count your other midterm exam score twice. There will be no make up for the final exam.

Grades

Grades will be calculated according to percentages in each of the four categories. The categories and their weights are:

• Homework: 20%
• Quizzes:20%
• Midterm exams:2x 15% each=30%
• Final Exam:30%

Your final grade will be based on the rough breakdown of:

• A: 90-100%
• B: 78-90%
• C: 64-78%
• D: 50-64%
• F: <50%

This may be subject to change depending on distribution, but my policy is absolute in the following way: I will not pass any student with an average lower than 50%.
