------------------------------------------------------------
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, as long as there is no violation
of the Collaboration policy of the Syllabus. 
Dept grade policy guidelines are then applied.


ADJUSTMENT-1
Students with  
  i. < 500 pts  AND
 ii. # points >= 50% of top student's points, AND
iii. Final >=  50% of top Final exam grade 
also get a C even if they have < 500 pts.

ADJUSTMENT-2
  A violation (or violations) of the Collaboration policy 
adjusts grades lower.
  Dean of Students office messages adjusts grade lower.

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).
