RULE 1.
Final Exams at 25% of 333  = 83.25 receive an automatic F per Syllabus(Handout 1).
If letter grade is assigned here it is final; for all other cases it will involve RULES 2-5.

RULE 2.
Students are then groupped 'curve like' per half of standard deviation (usually 70pts).
Final Letter grades are decided for the remaining non-RULE 1 students.

ADJUSTMENT-1
RULE-2 students below 500 are added excess points to determine if they can 
be assigned a C.

ADJUSTMENT-2
RULE-2 students with (< 500 pts) but with  points at least  50% of top student 
points and at MORE than 50% of top Exam3 grade  also get a C even 
if they have < 500 pts.

ADJUSTMENT-3
Students at more than 500 points use excess points provided Exam 3 grade is 
around the level of the Exam 3 grade of students in the upper group.

Average         =  Sum of grades divided by number of exams
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).
