HW    = average of your 4 hw scores (on blackboard)
exam1 = first midterm score
exam2 = second midterm score
MOM:    if MoM = Y, I double-counted your high exam score and dropped
        your lower one.
ctzn  = (see below)
ph.1  = average of I.1-I.4 project scores (on blackboard)
ph.2  = average of II.5a, II.5b and II.6 project scores (on
        blackboard) 
ph.3  = (see below)

For ctzn (citizenship):
  * you got 70 points if you turned in peer evaluations
  * you got 10 more points for each of three times
    during the semester that I took careful attendance 
    in class (you were in class or arranged your absence
    in advance with me)
so the total possible is 100.

ph.3 = (talk1 + talk2 + 4*paper)/6 
  where 'talk1' and 'talk2' are your scores on the two presentations,
  and 'paper' is your final paper score (all on blackboard). [this
  means that each talk was worth 5% of your final grade, and your
  final paper was worth 20% of your final grade.]

These were used in a weighted average with weights as prescribed in
the syllabus:

   hw exam1 exam2  ctzn  ph.1  ph.2  ph.3 
   20%  15%    1%   10%    5%    5%   30% 
 
to produce a "semester score" for you.  Letter grades were determined
as follows:

  Score Range		Letter Grade	Number given
  90-100		A               17
  80-89			B		16
  65-79			C		3
  50-64			D		2
  0-49			R		1

have a great summer!
