 Examination criteria: The final grade will be computed using the following weights.
 Attendance: 5 percent
 Online homework: 10 percent
 Quizzes: 10 percent
 Projects: 10 percent
 Test 1: 20 percent
 Test 2: 20 percent
 Final exam: 25 percent
 Grading:
 A: 90 percent (or better)
 A: 88 percent (or better)
 B+: 86 percent (or better)
 B: 80 percent (or better)
 B: 78 percent (or better)
 C+: 76 percent (or better)
 C: 70 percent (or better)
 C: 68 percent (or better)
 D+: 66 percent (or better)
 D: 60 percent (or better)
 Attendance: Attendance is required and contributes to the final grade. Three classes may be missed without affecting this grade. A student who was absent in more than half of the class meetings automatically has failed the course, regardless of his other scores.
 Homework: Every week, there will be an online homework assignment, which uses the online homework system WeBWorK at http://ww2.math.buffalo.edu/webwork2/2014_1_MTH306_Sommerhauser/. For this system, your username is your UBIT name, and your password is your UB person number. The time frame for this homework begins on Monday after the lecture, and ends the next Monday one hour before the lecture.
However, late homework is accepted for another week, but only for 75 percent of the point value. This grace period also ends on Monday one hour before the lecture.
Moreover, there will be a reading assignment in every lecture.
 Recitation sessions: The recitation sessions begin in the second week of classes. During the recitation sessions, you will either take a quiz or work on a computer algebra project using the computer algebra system MAPLE, which can be downloaded at http://www.buffalo.edu/ubit/serviceguides/software.html. Both quizzes and computer algebra projects will contribute to your final grade.
 Policies: Eating, drinking, and smoking is not permitted in the classroom. Moreover, the use of electronic devices such as cellphones, laptop computers, calculators, and ipods is not permitted unless explicitly allowed by the instructor.
 Tutoring: Mathematics tutors are available at no charge in the Mathematics Help Center in Room 110 of the Mathematics Building, which is open Monday to Friday from 9 am to 12 m and 1 pm to 3 pm on days when classes are in session.
