You can always do more homework problems!
You may need to practise the material
if you want to remember it
for the final exam,
a subsequent course, or the rest of your life.
If you bought MyMathLab access with your course textbook (or separately),
then you can find supplementary problems
through
the
Moodle page.
(However, MyMathLab is *not required* for this section.)
