Quizzes, Tests, and grading

In this course we will try to do many examples and problems. Example problems will be worked out in every class. You will be expected to work on them during class and do other recommended problems at home, by yourself or with your study group. Please keep checking UPDATE page for problems and notes of what was done in class.
There are also practice assignments on webassign. If you can't access webassign then you can do the problems from the book. It is highly recommended that you form a study group and meet with students in your study group atleast once a week.

There will be 3 tests for 100 points each. Best 2 will count

Writing only answers in test, will fetch only small amount of credit. Please always explain your work and present solutions step by step. This will also help you to get partial credit even if answer is wrong.

There will be weekly quizzes based on homework problems which will be assigned after each class, on update page. At end of course a few quizzes will be dropped and some quizzes may be counted as extra credit. Will tell you how many later in the course.
