First figure your homework grade.  If the possible number of
Mastering Physics (MP) points is 1875 then your HW percentage is
your total MP points divided by 1685 (89.9% of the total possible
MP points of 1875) then multiplied by 100%, with a maximum of 100%.
As an example, say you have earned 1482.8 Mastering Physics points for the
session.  Your HW percentage would then be:

                      1482.8/1685  = 88.0%

HW is worth 8 points overall, so you would have earned 7.04 HW points
(i.e. 88.0% of 8)

  750 HOMEWORK POINTS ARE REQUIRED FOR A PASSING GRADE IN THE COURSE.
          LESS THAN 750 HOMEWORK POINTS IS AN AUTOMATIC E.
             (750 is 40% of the assumed total of 1875.)

     Now figure your TP grade.  There will be about 60 TP questions
for the session, so a total of about 180 TP points are possible.  However,
we will figure the final TP percentage out of only 162 points (or about
90% of all possible TP points should the number of possible TP points
change; we actually had 76 questions this session, for 228 possible 
points, and we figured the final TP percentage out of 200 points).
Once again, you can't get more than 100%.  Say you have earned
133 TP points for the session.  Your TP percentage would be

                        133/162 = 82.1%.

TP is worth 5 points overall, so your TP points for the semester are
4.10 (133/162 times 5).

     Now figure your quiz total.  We grade quizzes out of 10 points
and we take your best 15 of 21 quizzes.  Say your best 15 quizzes total 
up to 118 points.  Your quiz average is then 118/15 = 7.87.  Quizzes are 
worth 7 points overall so your quiz points for the session are 5.51 
(78.7% 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 3*12 points and Lecture Quiz halves are worth 44 points.
You may keep any three MC halves and any three Lecture Quiz 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 three MC halves you
keep divided by 3, plus the total of the three LQ halves you keep 
divided by 3.  For example, say these are your test scores:

           TEST 1      TEST 2      TEST 3      TEST 4
         LQ    MC    LQ    MC    LQ    MC    LQ    MC 
         36     8    23     9    38     5    33     9

With these scores you would want to drop TEST 2 Lecture Quiz and
TEST 3 MULTIPLE CHOICE.  Your test average (out of 80 possible) would be:

 (36 + 38 + 33)/3 + (3*8 + 3*9 + 3*9)/3 = (107/3)+(26) = 61.67/80 = 0.7708 
                                                                or 77.1%

Tests are worth 80 points overall, so your total test points are 61.67 points

     This makes your overall total 7.04 + 4.10 + 5.51 + 61.67 = 78.2.  
What will be your final letter grade?  That depends on what the final
grade scale is.  I start with no curve.  That is 

                 80 and above           A
                 65-80                  B
                 50-65                  C
                 40-50                  D
                 below 40               E

If the class average is 65 or higher, there is no change.  If the
class average falls below 65, I feel obliged to relax this scale
somewhat.  Look at
