Below is the distribution of the grades with some statistics (the scores
were out of a maximum 10 points) ::


A : >= 9          : 17 records : 38.6 %
B : >= 8 and < 9  : 20 records : 45.4 %
C : >= 7 and < 8  :  6 records : 13.7 %
D : >= 6 and < 7  :  1 record  :  2.3 %
---------------------------------------
Total :             44 records   : 100 %

Mean  :  8.62/10 = 86.2 %

About the grading itself, basically, every question was worth 1 "point". 
 
   * 6 "points"  = 11/10 
   * 5 "points"  = 10/10    
   * 4 "points"  = 9/10  
   * 3 "points"  = 8/10  
   * 2 "points"  = 7/10  
   * 1 "point"   = 6/10
