        --- Subject to change ---
N              = 37
Average        = 634 (without PrP excess points)
Average        = 681 (with    PrP excess points)
Stand Deviation= 154-161 (with or without PrP excess points)

------------------------------------------------------------
RULE 1.
Students are groupped 'curve like' per half of standard deviation 
(usually 70-90pts).  Final Letter grades are decided in six group
(A,B+,B,C+,C,F) under the provision that  students 500 points 
or higher can NEVER get an F. Dept grade policy guidelines are 
then applied.

ADJUSTMENT-1
RULE-1 students below 500 are added excess points to determine if 
they can be assigned a C. 

ADJUSTMENT-2
RULE-1 students with (< 500 pts) but with  points at least  
50% of top student's points and a Final   at MORE than 50% 
of top Final exam grade also get a C 
even if they have < 500 pts.

ADJUSTMENT-3
Students at more than 500 points utilize excess points provided 
  (i) Final Exam grade is around the level of the final exam grade 
  of students in the upper group,  
  (ii) A violation (or violations) of the Collaboration policy 
has not been detected.

ADJUSTMENT-4
  A violation of the Collaboration policy adjusts a grade lower 
after consultation with the Dean of Students.

N               =  number of students taking the exam
Interval        =  0 to maxpoints possible for exam (as in Handout 1)
Average         =  Sum of exam grades divided by N
Stand Deviation =  Shows dispersion of grades. Roughly, 2/3 of the grades are
                   within 37 +/- 12 , and 95% within  37 +/-  2*12 if ave is 37 
                   and std 12
Median          =  Half of the students got that much or less 
                   (and half, more than that).
