**DISCLAIMER:**
Ignore this section (if you can). It is *not official*.
This course has no official letter grades for exams.
At the end, *number grades* for homework, midterms, and
the final are added, and letter grades for the course are based
on that one number (total score for all work).

That having been said, you may take as a rough guide *for this
exam only* that 90-100 is an A (including A-), 80-89 is a B
(including B+ and B-), and 50-79 is a C (including C+ and C-).

This entails *no promise* to use the same percentage ranges
on the second midterm or on the final.

Repeating what the disclaimer says in other words, we average
*numbers* not *letters*. Don't come to me saying
that you had an A on the homework and both midterms and a B on the final,
so how could you possibly get a B for the course. If the midterms were
both 90, the homework was 90, and the final was 80, your total grade is

0.25 * 90 + 0.25 * 90 + 0.20 * 90 + 0.30 * 80 = 87which is in the B range (assuming we use the same ranges throughout, which as stated above we do not promise to do).
