How to Calculate CGPA in Engineering?

CGPA is calculated by adding the credit points for every subject and dividing the total by the accumulated credit points held for the semester. The credit points allotted to each subject is 10 points.

CGPA stands for Cumulative Grade Point Average. It is the globally accepted weightage system for engineering and other courses. While the system of counting may differ between countries, CGPA is the common and standard system of calculating marks worldwide. The admission to the institutes for higher education as well as MNCs demand the CGPA from a candidate.

Students who are wishing to get enrolled in engineering courses like civil engineering, electrical engineering, electronics engineering and other fields, must read this article thoroughly to understand the CGPA system and its importance in the academic world in the present times. They must understand how to calculate CGPA in engineering. This article will discuss the CGPA weightage system in detail.

What is CGPA?

CGPA is the abbreviated form of Cumulative Grade Point Average. IT is the standard grade or credit point system that is used to calculate the marks obtained in a semester for engineering or any other course. The CGPA for a student is obtained by calculating the total marks obtained by a student divided by the total credit points or grade points allotted to each subject, which is 10 points.

The CGPA system of score calculation is a globally accepted system. It helps in a uniform calculation of weightage. The colleges and other higher study institutions request the CGPA instead of grades and percentage at the time of admission. For engineering courses, a knowledge of CGPA and how to calculate the CGPA is essential.

How to Calculate CGPA?

Under the CGPA system, the grades are calculated for a section of marks. For example, the marks bracket 97-100 is grade A+, 93-96 is grade A, 89-92 is grade A-, and so on. The aggregate marks are calculated on the basis of total accumulated grade points.

Thus, the total marks scored in all the subjects is divided by the total number of subjects in the semester to get the grade scored in the semester. The CGPA can be converted to marks and percentage, and CPI to percentage.

Here is the CGPA Formula:

CGPA = Total GPA (Grade Point Average) of all the semesters / Total number of credit hours

The best scores in engineering in terms of CGPA is 8 and above.

How to Calculate CGPA in Engineering Colleges in India?

The CGPA calculation in the Indian engineering colleges is somewhat different from one another. The generalised method for the calculation of CGPA in the engineering colleges in India is:

Total Percentage/9.5 = CGPA

For instance, if a student has scored 400 marks in a total of 6 subjects in the semester, then his/her CGPa will be calculated in the below mentioned way:

The percentage of marks scored is to be calculated first:

400/600 * 100 = 66.66%

In order to calculate the CGPA, this percentage has to be divided by 9.5:

66.66/9.5 = 7.02 CGPA

The Indian engineering colleges follow two distinctive systems of gradation- Absolute Grading System and Relative Grading System. As per the Absolute Grading System, the total percentage attained by a student is calculated.

In the Relative Grading System, the individual performance is highlighted with respect to percentage scored by others.

To understand the Relative Grading System, a table has been provided below:

Grade	Numerical Value
A+	10
A	9
B	8
C	7
D	6
E	5
F	0

Where, 

91-100 = A+

81-90 = A

71-80 = B

61-70 = C

51-60 = D

41-50 = E and so on.

If a student scores 64 in Chemistry and 95 in Physics, the credit points will be 9 and 10 respectively for Chemistry and Physics.

Students can find below how to calculate CGPA in engineering:

The CGPA will be: (credit points for the subject * points received by the student) / total credit points

How is CGPA Calculated in Engineering Colleges Abroad?

In order to understand the CGPa calculation in engineering colleges abroad, the concept of SGPA has to be understood. SGPA stands for Semester Grade Point Average. The SGPA is calculated by multiplication of the credit points by 10. CGPA is calculated by credit points.

In simpler terms, the overall CGPA is the average of SGPA. The SGPA of all the semesters are to be added and then the total is to be divided by the number of semesters. This will give the CGPA.

While some universities abroad calculate the CGPA using 10, others calculate it using 4. 

For example, the table below shows the SGPAs scored by a student in 8 semesters.

Semester	SGPA
1	8
2	9
3	8
4	7
5	9
6	8
7	7
8	9

To calculate the CGPA for the student, the following method will be used:

CGPA= (Sum of SGPA for total no. of semesters) / (Total no. of semesters) = (8+9+8+7+9+8+7+9) / 8 = 8.1

Advantages of the CGPA System

The CGPA system of score calculation has numerous advantages. This is the reason why it is important to know and understand this system, especially for a student who has enrolled in the engineering course.

The advantages of the CGPA system of grading has been enlisted below:

• The grading system will help the students understand their points of strength and weaknesses and address them accordingly.
• The uniformity of grading allows the universities to judge the results of the applicants in a more efficient way.
• It ensures the overall evaluation of the students on the basis of their year round academic performance including the semesters and other tests.
• This system is much easier for the higher study institutions and employers to understand rather than any complex scoring system.
