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.
