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.

Grade Point Average (
SGPA) calculation :
A
SGPA will be computed for each
semester. The SGPA will be calculated as follows:
where
Ci =
Credit for the course
GPi = Grade Point obtained for the course and
n = Number of subjects registered for the semester.
