Class Meetings              Monday & Wednesday, 11 a.m. to 12:15 pm, CR 5117

Math 150b is required, and Math 250 is helpful for this course

There will be two midterm exams, each worth 100 points, and a final exam worth 200 points.  There will also be some short quizzes, each worth 30 points. Class participation will resolve borderline grades, with the possibility, for example, of a final B+ grade becoming an A-, with constructive participation and volunteering solutions in class.  Plus (+) and minus (–) grades will be assigned for this course.  The dates of the midterms will be announced in class. 

Final Exam: Wednesday, May 15, 2019, 10:15 a.m. to 12:15 p.m.

Homework will generally be assigned each class meeting and will be posted on this webpage (see below).  It is extremely important to keep up with the assignments.   I encourage you to work together with other students in the class on the homework.  Homework will not be collected, but problems on quizzes will be taken from the homework.

Student behavior, academic dishonesty, university policies

Please arrive on time and avoid leaving early.  No text messaging.  Cell phones should be turned off during class and all exams and quizzes.  Seats may be reassigned during exams, and you must leave your ID on top of the desk.  You will need to turn in an exam or quiz if you leave the room, so go to the bathroom beforehand.  Academic Dishonesty is covered in Appendix C of the CSUN catalog. Academic dishonesty will be reported to the Office of Student Affairs.  For information about CSUN's policy for academic dishonesty, see:

Note also that according to CSUN policy, a grade that is sanctioned due to academic dishonesty cannot be replaced by subsequent course grades:
