average grade is less than 40, you will receive a letter
grade FF
 If you do not complete the following requirements, you
will receive a letter grade VF:
 One of your midterm exam grades must be more
than 30

Cheating and Plagiarism
 Do not!
 Studying together to understand the material is fine,
but the work you hand in is to be your own.
 No cheating will be tolerated: A letter grade of F will
be given!
 You can constitute a group of maximum three students
to submit assignments. You may submit a unique report
for your group (of course plagiarism among assignment
groups is strictly forbidden).
