Let’s explain common method of Calculation of Cumulative Grade Point Average (CGPA). CGPA is an accumulation of all your grade points divided to every single credit you take. CGPA is calculated based on all subjects that you take. Each subject usually carries a credit value. Some less important subjects carry between 1 to 2 credits; more important ones carry 3 to 4. There are subjects categorized as "compulsory attendance only" or “compulsory for passing only” which usually carry 0 credits. These subjects hold no value, but failing it (due to poor attendance or whatsoever) will still hold you down from graduating successfully. Calculation of GPA: For each subject that you have successfully taken, a grade will be issued after the final exam. These grades each carry a specific point value i.e. A carries 4, B carries 3, C carries 2, D carries 1, and E carries 0 . Each of these points will be calculated based on the credit rating of each subject, and later summed up to give you your GPA for that particular semester.

For example:
Semester 1
Subject M (6 credits): B = 3.00
Subject N (2 credits): A = 4.00
Subject O (3 credits): C = 2.00
(6 x 3.00) + (2 x 4.00) + (3 x 2.00) = 32 total grade point for 11 credits.

Hence, your GPA for semester 1 is: 32 / 11 = 2.91 GPA for semester 1.
Since this is your first semester, your GPA is also your CGPA.

Semester 2

Subject P (6 credits): A = 4.00
Subject Q (3 credits): B = 3.00
Subject R (3 credits): E = 0.00 (FAIL)
Subject S (2 credits): B = 3.00
(6 x 4.00) + (3 x 3.00) + (3 x 0.00) + (2 x 3.00) = 39 total grade point for 14 credits. Hence your GPA for semester 2 is: 39 / 14 = 2.79 GPA for semester 2
Now that this is your second semester, your CGPA will be calculated by combining the two. However; a direct average is wrong. CGPA is calculated not based on the average of GPAs per semester, but based on grade points per credit that you take. To calculate your CGPA based on the two semesters above:
[(total grade point for semester 1) + (total grade point for semester 2)] / total credit taken in all semesters
[(32) + (39)] / (11 + 14) = 2.84 CGPA


Now, let's try the next semester where you retake the failed subject:
Semester 3
Subject R (3 credits): A = 4.00 (REPEATED SUBJECT)
Subject T (3 credits): B = 3.00
Subject U (3 credits): B = 3.00
Subject V (3 credits): B = 3.00

(3 x 4.00) + (3 x 3.00) + (3 x 3.00) + (3 x 3.00) = 39 total grade point for 12 credits. Hence your GPA for semester 3 is: 39 / 12 = 3.25 GPA.

Now, how do you calculate your CGPA when you have a repeated subject? Here is the main rule: you recalculate the repeated subject by replacing the old grade with the new one. It means, in your CGPA calculation, you never failed your subject R, you actually scored A! let’s see what it looks like:
[(grade points for sem 1) + (grade points for sem 2 excluding the failed subject) + (grade points for sem 3)] / [(credit for sem 1) + (credit for sem 2 excluding the failed subject) + (credit for sem 3)]

[(32) + (39 - 0) + (39)] / [(11) + (14 - 3) + (12)] = 110 / 34 = 3.24 CGPA!

Another example:
If in one semester/quarter you took three classes worth 6 credit hours each, and you earned two "A's" and a "B" which, traditionally, hold numeric values of 4 and 3, respectively, then you first calculate the total number of quality points, like so:
6 x 4 = 24
6 x 4 = 24
6 x 3 = 18
----------------
TOTAL QPs = (24 + 24 + 18) = 66
Again, to calculate your GPA, you would divide the QPs by the total number of credits attempted for each letter grade earned (that is, A, B, C, D, or F), like so:
66 / 18 = 3.67
Thus, your GPA for that semester/quarter would be 3.67. To calculate CGPA, which is your cumulative GPA, you would do this for all classes that you have completed up to that point and in which you earned a grade of A-D or F.

Applicable system in University of Sindh Jamshoro under 2010 announcement:

Course Weightage-Credit Hour Each course carries certain credit hours assigned to it. One credit hour (C.H.) for a particular course is generally to be considered as fifty minutes (one period) of teaching per week. The number of credit hours indicates weightage of the course compared to other courses and also reflects number of hours of teaching of that course per week. Thus a course of 3 credit hours would mean a total of 3x16= 48 (credit hours assigned to the course multiplied by the number of weeks of semester) hours of actual teaching of that course in a semester. Laboratory course (Practical) upto 6 hours duration conducted once a week is assigned 1 C.H.

The credit hours are generally assigned as shown hereunder:- English and other ‘General Requirements’ courses 2-3 C.H. each course per semester

All supporting Minor courses in Arts 3 C.H. each course per semester

All supporting Minor courses in Science Theory 2 C.H. each course per semester

Lab. (Practical) 1 C.H. each course per semester
All courses of discipline in which Majoring:

For Arts/ Commerce & Business Admn/ Islamic St. 3 or 4 C.H. each course per semester

For Natural Science Theory 3/ 4 C.H. each course per semester

Lab. (Practical) 1 C.H. each course per semester

Master’s level or graduate theory courses are generally assigned 3/4 C.H weightage and laboratory (Practical) are assigned 1 C.H. or 2 C.H conducted up to 3 hour/ 6 hour duration per week respectively

Grade Equivalence
Equivalence between letter grading and numerical grading in most disciplines (except Pharmacy & Business Administration) will be as under:-

Grade Equivalence: General

Grade..... Numerical Value........Marks..........Remarks
A............4 to < 5..............80- 100%.....Excellent
B........... 3 to < 4...............60- 79%......Good
C.......... 2 to < 3.............. 50 -59%......Satisfactory / Average
D.......... 1 to < 2..............40-49%........Pass
F.......... 0.......................Below 40%.....Fail
I........... 0..........................................Incompl ete
W......... 0..........................................Withdra wn from course

R.......... 0...........................................Resear ch in Progress

Grade Equivalence for Pharmacy:
Grade.... Numerical Value.......Marks.............Remarks
A.......... 4 to < 5...............80- 100%..........Excellent
B........... 3 to < 4.............. 60- 79%............Good
C...........1 to < 1.............. 50 -59%........... Average
D.......... 0........................Bellow 50%........Fail

Grade Equivalence for *Business Administration programs:
Grade..... Numerical Value.........Marks.............Remarks
A................4 to 5..................87% and above.....Excellent
B................3 to 4..................72- 86%.............Good
C...............2 to 3...................60 -71%.............Satisfactory / Average
F...............0.........................Below 60%.......... Fail


Quality Point (Q.P)/ Grade Point
The quality point of the performance of a student is obtained by multiplying the numerical value (see table above) of the grade earned by a student with the Credit Hours of that course, e.g., an ‘A’ grade in a course of 3 C.H. would earn 4x3=12 Q.P. and a ‘D’ grade in the same course earns 1x3=3 Q.P/ G.P.
The Academic Council has however resolved that while converting numerical score into appropriate grade, e.g. ‘A’ where score is 87%, the range of grade value corresponding to the percentage score (i.e. 4.4) be reckoned with in future. It implies that, with score of 60 & 78%, both would have been assigned ‘B’ under old rules; however allowing proportionate numerical Grade Value, the two scores be assigned 3.0 and 3.9 grade point respectively thereby allowing the student the benefit of better performance in the later case. This revised system would also be helpful in scoring better G.P.A../ C.G.P.A.
The ready reckoner table for conversion of numerical score into proportionate grade point is reproduced hereunder:-

Grade Point Average (G.P.A)
It is an expression for the average performance of the student in the courses he has offered during one or two semesters or at the end of the entire course.
G.P.A.= Sum of all the Quality Points earned /Sum of the Credit Hours of all the courses offered

Calculation : Example
Course #......Credit Hrs......Score....Grade.....Grade Point.....QP......GPA
ENGL 101,,,,,,,,,3,,,,,,,,,,,,,,,,,68%,,,,,,B,,,,,,,,,, ,3.4,,,,,,,,,,,,10.2
ARAB 101 ,,,,,,,,,3,,,,,,,,,,,,,,,,57%,,,,,,C,,,,,,,,,,,2.7 ,,,,,,,,,,,,,8.1
ZOOL 101,,,,,,,,,3+1=4,,,,,,,,45%,,,,,,,D,,,,,,,,,,,1.5 ,,,,,,,,,,,,6.0
COMP 101,,,,,,,,,2+1=3,,,,,,, 80%,,,,,,,A,,,,,,,,,,,4.0,,,,,,,,,,,,12.0
BOTN 101,,,,,,,,,3+1=4,,,,,,,,50%,,,,,,,C,,,,,,,,,, 2.0,,,,,,,,,,,,8.0
Total,,,,,,,,,,,,,,,17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,44.3,,,2.61
Multiply Grade Point with the Credit Hours in each course, add up the cumulative Grade Points and divide by the Total Number of credit hours to get the G.P.A. per Semester. In the above example the G.P.A. is 44.3 divided by 17= 2.61
