All problems are taken from the textbook (Rosen),
§3.1 - 3.3. You should also practice the odd-numbered
problems in those sections, whose solutions you can check in the back
of the book, or review in more detail in the student solutions guide.
Practicing other even-numbered problems may also help you. Each
assigned book exercise is worth 5 points out of a total of 100.
We are still using the same optional collaborative homework policy
that we used in the previous assignments. (Group work is permitted,
if you turn in a joint assignment.)
Unless otherwise indicated, the listed extra credit exercises are
each worth 5 extra points out of the 100, up to a maximum score of
100%.
