To calculate your cumulative GPA, you will
need to locate the total GPA hours and total Quality Points (QP) on your
transcript from each institution you attended and add them together.
If the transcript does not include the
total quality points, you can calculate them by multiplying the points
for each grade times the total credit hours for the course.
See below:
A = 4 pts
B = 3 pts
C = 2 pts
D = 1 pt
F = 0 pts
CR or P = Not Included
Exclude repeated courses
(Include only the 2nd
grade) 
Example:
Course Grade = A (4 Pts)
Course Hours = 3
QP for course = 3 x 4
Result = 12 QP

Divide the total quality points by the
total number of GPA hours to determine GPA. See example below:
UALR = 12 GPA Hours with 48 QP
PTC = 3 GPA Hours with 9 QP
UCA = 5 GPA Hours with 10 QP 
Total GPA Hours = 20
Total QP = 67
Cumulative GPA = 67 / 20
Result = 3.35 GPA 
To calculate your general education
prerequisite grade point, do the same as above using only the
prerequisite courses (excluding the elective hours.)
