Sapling on-line homework, Ch 12B, deadline, etc.

[Robert Zellmer]

I mentioned this in class and thought I had sent it in a previous
e-mail.  Homework 12B does NOT count toward your grade.
It's about polymers.  This material is in Chapter 12 of the book.
I did briefly mention polymers in lecture on Monday.  It's interesting
and you may want to look at it.

Also, the math review was in the "optional" section before the
actual homework problems.  It had been set to graded but should
not have been.  I reset it to ungraded.

The final cutoff is today at 6 PM.  You won't be able to do the
on-line homework after that (HW12A).  I realize this material
isn't on the final but you do still have homework for credit for it.
