```     First figure your homework grade.  Keep your returned HW papers
running total of your HW grades, plus a running total of the number
of HW points possible.

Your HW percentage is your total number of HW points divided by
the number of HW points which are possible.  If I have counted correctly,
there are 310 possible HW points for the entire semester.  However,
we will figure the final HW percentage out of only 250 points.  You
can't get more than 100% though, so once you have 250 points you don't
need to turn in any more HW, unless you just like to have your HW

As an example, say you have earned 240 HW points for the semester.

240/250  = 96%

HW is worth 10 points overall, so you would have earned 9.6 HW points.
We round all point calculations to the nearest tenth of a point.

and we take your best 10 of 12 quizzes.  Say your best 10 quizzes total
up to 79 points.  Quizzes are worth 10 points overall so your quiz
points for the semester are 7.9.

after everybody has given their demo; so, until then, in order to get
50 points.  Say your demo grade is 42.  Since the demo problem is
worth 5 points overall, your overall demo point total is 4.2.

Now figure your test total.  Take your best 4 tests and average
them and mutiply by 0.6.  For example, say your test grades are 79,
85, 89, 72, and 95.  Your test average is then

(79+85+89+95)/4 = 87

We now multiply by .6 since the Tests are worth 60 points overall.

87 times 0.6 = 52.2

OK, now you have your pre-exam total.

HW      9.6
QUIZ    7.9
DEMO    4.2
TEST   52.2

total   73.9

The pre-exam maximum is 85 points, so your pre-exam percentage is

73.9/85 = 86.9%

Will you be able to get an A?  That depends on what the final

90 and above           A
80-90                  B
70-80                  C
60-70                  D
below 60               E

If the class average is 75 or higher, there is no change.  If the
class average falls below 75, I feel obliged to relax this scale
somewhat.  Look at
```
last year's web page
```to get an idea for what this year's scale might be.  I will make
a guess at the final grade scale during the week before the exam,
but the true final grade scale ultimately depends on overall class
exam performance.

Let's get back to our example.  You have 73.9 points going in
to the exam.  The exam is worth 15 so the best you can do is 88.9,
not enough to get an A if the class average is 75 or higher.  On
the other hand, you need at least 6.1 points from the exam to insure
yourself of a B.  The exam consists of 40 multiple choice questions,
so you need to get at least (6.1/15)*40 right, or 17 out of 40, to
insure yourself of a B.
