COURSE STRUCTURE

 

Homework is due each Monday. See the course schedule for specific assignments. Selected problems will be graded each week - not the entire assignment. The answer is not the most important thing. They can be obtained just about anywhere (a classmate or the solution manual for example) and many problems can be worked in multiple ways. No late homework is accepted; however, the two lowest homework scores will be dropped (for example if you missed two homework assignments, those scores of 0 will be dropped).

 

There will be 2 regular exams and a comprehensive final. The course will cover portions of Chapters 1-3 of the text.  Each regular exam will account for 25% of your grade. The final will account for 35%. Homework will account for 15%. There are no make-up exams. If you know you cannot make a given exam, arrangements can be made to take the exam early, but never late.  If you miss an exam, then the other grades will take on proportionally more weight. The down side is that you will get no benefit of doubt at the end of the semester. For example if you are a borderline A-B and you have missed an exam, you will receive a grade of B for the semester. Under no circumstances can you miss the final.

 

Free tutoring is available in the Mathematics Learning Center. See the Center door/website for actual hours.
