First figure your homework grade.  Keep your returned HW papers
in case your instructor makes a mistake in recording your grade.
Also check your recorded grades occasionally on the web.  

     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 500 possible HW points for the first summer session.  However,
we will figure the final HW percentage out of only 450 points.  You 
can't get more than 100% though, so once you have 450 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 400 HW points for the semester.
Your HW percentage would be:

             400/450  = 89%

HW is worth 25 points overall, so you would have earned 22.2 HW points.
We round all point calculations to the nearest tenth of a point.

     Now figure your test total.  In the summer there are four tests
in 2 parts each, for a total of 8 parts, or "halves".  You may keep any 
six halves except that you must keep at least one part of test 4, which 
serves the purpose of an exam.  Multiple Choice halves are worth 60 
points each and Problem halves are worth 65 points each.  Your test
total is the total of the six halves you keep, divided by the total
points possible for those six halves, times 75.  For example, say
these are your test scores:

          TEST 1      TEST 2      TEST 3      TEST 4
         MC   PROB   MC   PROB   MC   PROB   MC   PROB
         45    51    40    33    45    47    30    49

With these scores you would want to drop TEST 2 PROBLEMS and TEST 4
MULTIPLE CHOICE.  Your test total would be:

      75 points * (45 + 51 + 40 + 45 + 47 + 49)/(3 * 65 + 3 * 60)

            = 75 (277/375) = 75 (.7387) = 55.4

     This makes your overall total 22.2 + 55.4 = 77.6.  What will
be your final letter grade?  That depends on what the final
grade scale is.  I start with no curve.  That is 

                 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
or summer 1996 web page
to get an idea for what this year's scale might be.
