In a hybrid
grading system, we use a combination of both
absolute and relative grading
systems.
-
The two highest grades
and the lowest grade are earned and the grades
in between are awarded.
-
To earn A grade, student
has to secure >= 85 and < 90 aggregate
marks.
-
To earn A+ grade,
student has to secure > = 90 aggregate marks.
Once highest and lowest grades are
identified, the remaining grades are then
awarded by plotting the histogram of number of
students (Y axis) and marks (X axis) and
identifying the cluster of students. These
clusters of students are identified based on
gaps and dips in the histogram.
The
list of letter grades and its connotation are
shown in table 1.
