Math 246 Quizzes and Homeworks, Fall 2010
There will be eleven short in-class quizzes based on homeworks. Homeworks will not be collected.
- Quizzes on material covered on the first in-class exam (23 September)
- Quizzes on material covered on the second in-class exam (28 October)
- Quizzes on material covered on the third in-class exam (2 December)
No calculators, books, or notes may be used during quizzes.
All items except pens, pencils, and erasers must be off the
desktops.
Quizzes will be given at the beginning of the class period.
They will be short. Please be sure to arrive on time!
These eleven in-class quizzes will be worth 10 points each. Your
ten best quiz scores will go toward your course grade. No make-up
quizzes will be given.
If the University closes on the day of a scheduled quiz and no exam
is scheduled that week then the quiz will be given the next time the
class meets. If the University closes on the day of a scheduled quiz
and an exam is scheduled that week then the quiz will be cancelled.
HOMEWORKS
Below are the weekly homework assignments. These will not be
collected. However the material from the homework will appear on
the quizzes and exams. The dates given are when the material is
first scheduled to be tested on either an exam or a quiz. Quiz
material should be covered during the lectures and discussion
sections just before the quiz. You are responsible for the
material even if the University closes on the day of the
discussion section. It is a good idea to look over all material
before it is covered in the lectures.
These assignments are subject to changes announced either in class or
on this webpage.
