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 320 possible HW points for the second summer session.  However,
we will figure the final HW percentage out of only 288 points.  You 
can't get more than 100% though, so once you have 288 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 256 HW points for the session.
Your HW percentage would be:

             256/288  = 88.9%

HW is worth 8 points overall, so you would have earned 7.11 HW points.

                           AUTOMATIC E.

     Now figure your PRS grade.  There will be about 50 PRS questions
for the session, so a total of 150 PRS points are possible.  However,
we will figure the final PRS percentage out of only 135 points (or about
90% of all possible PRS points should the number of possible PRS points
change).  Once again, you can't get more than 100%.  (There ended up
being only 40 PRS questions this summer, so a total of 120 PRS points
were possible; we figured the final PRS percentage out of only 108 
points.  So, in what follows below, divide by 108 instead of 135. 
Thanks. GBA)  Say you have earned 111 PRS points for the session.  
Your PRS percentage would be

                        111/135 = 82.2%.

PRS is worth 5 points overall, so your PRS points for the semester are
4.11 (82.2% of 5).

     Now figure your quiz total.  We grade quizzes out of 10 points
and we take your best 12 of 16 quizzes.  Say your best 12 quizzes total 
up to 94 points.  (There ended up being on 15 quizzes this summer; we 
took your best 11 of those 15 quizzes.  GBA)  Your quiz average is then 
94/12 = 7.83.  Quizzes are worth 7 points overall so your quiz points 
for the session are 5.48 (78.3% of 7).

 Now figure your test total.  In the summer there are four tests
in 2 parts each, for a total of 8 parts, or "halves".  Multiple Choice
halves are worth 60 points and Problem halves are worth 65 points.  You 
may keep any three MC halves and any three Problems halves except that 
you must keep at least one part of test 4, which serves the purpose of 
an exam.  Your test average is the total of the six halves you keep, 
divided by the total points possible for those six halves.  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    56    40    38    45    52    30    54

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

   (45 + 56 + 40 + 45 + 52 + 54)/375 = (292/375) = 0.7787 or 77.9%

Tests are worth 80 points overall, so your total test points are

                 80 * (0.7787) = 62.29 points

     This makes your overall total 8.9 + 7.8 + 62.3 = 79.0.  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 summer's web page 
                 or  summer 2005 web page 
                 or  summer 2004 web page 
                 or  summer 2003 web page 
                 or  summer 2002 web page 

to get an idea for what this year's scale might be.
