To Pass a particular subject you have to get 

(Assingments+GDBs+Quizzes)+ MidTerm Collectively  = 20 %  at least     (collectively) 

(Note:- you will not pass if you get 20% only in midterm....and zero in Assingments+GDBs+Quizzes....Because collective marks are not 20%)

                   +

Final Term  = 20 %   at least

             = 

And  OVER ALL Percentage Should be .....At least 40 % .....To pass a course...

To get a Degree You need to earn atleast 2.25 CGPA

Grades, Grade Points and Grade Point Average (GPA): 

(i)   Grade and Grade Points: Grade of a course is awarded by teacher, recorded as evaluative and their symbols/letters used are listed below; whereas quality of achievement in a course is measured as Grade Point, that is, points per course hour assigned to a passing grade, indicating numerical value of the subject grade.
(ii)  Grade Point Average (GPA): It is widely accepted as a measure of academic achievement. GPA is calculated by dividing the total number of grade points earned by the total number of letter graded credit hours attempted. Each grade has a point value as follows: A=4, B=3, C=2, D=1, and F=0. W for withdrawal and I for Incomplete may also be used.      
Maximum grade point average=4.00   
Minimum cumulative grade point average for obtaining a degree =2.25

Grade	Value	Marks Obtained	Remarks
A	4.00	80-100 %	Excellent
B	3.00-3.93	65-79 %	Good
C	2.00-2.93	50-64 %	Satisfactory
D	1.00-1.90	40-49 %	Pass
F	0.00	Below 40 %	Fail

(Fractional marks to be rounded to the nearest whole number)
GPA of a semester is calculated as: multiply each grade point you receive by the number of credit hours for that course, add up the totals, and then divide by the total number of credit hours taken in that semester.
Cumulative Grade Point Average: Cumulative grade point average (CGPA) is the weighted mean value of all grade points earned by enrollment or by examination in courses at VU.   
(Explanation: GPA and CGPA includes the number of credit hours at VU for a letter grade even if a grade of “F” was earned).   
The cumulative grade point average (CGPA) will be calculated on the basis of the following formula:

CGPA = Sum(Credit Hrs for course X Grade Point obtained in the course) / Sum(credit Hrs)
with the sum being taken over all courses taken by the student with the specification that repeated courses shall be counted once only.  
(Explanation: If a student repeats a course, it will only be counted once towards the grade point and that will be calculated in the CGPA)
====================================================================

 Improvement of ‘D’ Grade:

(i)     In any of the subsequent semesters a student may repeat once, those courses of the previous semester(s) in which he/she had secured the lowest grade i.e. “D” only. However, a student is not allowed to improve ‘D’ grade of a deficiency course qualified.
(ii)  Any improved grade will substitute “F” and “D” grades of the previous Semester for calculating CGPA but “F” and “D” grades will form part of the transcript.

Below is the 20% Rule Explained by VU

20% Rule for passing an Exam

There is requirement of passing a subject that one student should be consistent in his studies through out. Therefore you are required to get 20% marks in rest of the items like assignments, midterm, discussions etc and at least 20% in final exam. This will make you eligible to pass a subject and then if you secure marks more than 40% overall while fulfilling the 20% criteria first then you would be considered as pass. Marks distribution:

Assignment Mid Final Marks Final Score 15% 35% 50% 100%

For passing a course you are required to get 20% marks overall in all items like assignments, discussions, midterm etc and at least 20% in final exam. Rest marks= sum of all items like assignments, discussions, midterm etc Rest Percent= sum of all items percentage like assignments, discussions, midterm etc.
