VTU SGPA to Percentage Formula
VTU follows a specific formula to convert SGPA to percentage. The official formula used by VTU is:
This formula is applicable to all regulations of VTU (including 2015, 2017, and 2018 schemes) and its affiliated colleges across Karnataka.
Example Calculations
Let's understand how to convert VTU SGPA to percentage with some examples:
Example 1: Converting SGPA 8.5 to Percentage
Using the formula: Percentage = (SGPA - 0.75) × 10
Percentage = (8.5 - 0.75) × 10
Percentage = 7.75 × 10
Percentage = 77.5%
Result: An SGPA of 8.5 at VTU is equivalent to 77.5%.
Example 2: Converting SGPA 7.2 to Percentage
Using the formula: Percentage = (SGPA - 0.75) × 10
Percentage = (7.2 - 0.75) × 10
Percentage = 6.45 × 10
Percentage = 64.5%
Result: An SGPA of 7.2 at VTU is equivalent to 64.5%.
VTU Grading System
VTU follows a 10-point grading system. Here's the complete grading scale used by VTU:
| Range of Marks | Letter Grade | Grade Points | Result |
|---|---|---|---|
| 90-100 | S (Outstanding) | 10 | Pass |
| 80-89 | A (Excellent) | 9 | Pass |
| 70-79 | B (Very Good) | 8 | Pass |
| 60-69 | C (Good) | 7 | Pass |
| 50-59 | D (Average) | 6 | Pass |
| 45-49 | E (Pass) | 4 | Pass |
| 0-44 | F (Fail) | 0 | Fail |
Note that VTU has a passing threshold of 45%, which corresponds to a grade of 'E' and 4 grade points. Any score below 45% results in an 'F' grade, requiring the student to reappear for the examination.
How VTU Calculates SGPA
SGPA calculation at VTU follows these steps:
- Each course is assigned credit points based on the number of lecture/tutorial/practical hours per week.
- Students are awarded grade points (GP) for each course based on their marks.
- The credit points for each course are calculated by multiplying the grade points obtained by the course credits.
- The SGPA is calculated using the formula:
Example of SGPA Calculation at VTU
Here's an example of how VTU calculates SGPA for a student in a semester:
| Course | Credits | Marks Obtained | Grade | Grade Point (GP) | Credit × GP |
|---|---|---|---|---|---|
| Engineering Mathematics | 4 | 82 | A | 9 | 36 |
| Data Structures | 4 | 75 | B | 8 | 32 |
| Computer Networks | 3 | 90 | S | 10 | 30 |
| Operating Systems | 3 | 65 | C | 7 | 21 |
| Programming Lab | 2 | 85 | A | 9 | 18 |
| Total | 16 | - | - | - | 137 |
SGPA = Total(Credit × GP) / Total Credits
SGPA = 137 / 16 = 8.56
Once you have the SGPA, you can convert it to percentage using the VTU formula:
Percentage = (8.56 - 0.75) × 10 = 78.1%
VTU Schemes and Regulations
VTU periodically updates its schemes and regulations. The current and recent schemes include 2018, 2017, and 2015 schemes. While the grading system remains largely the same across these schemes, there might be minor variations in credit distributions and evaluation methods.
The 2018 scheme is the latest scheme implemented by VTU. Key points include:
- Adopted outcome-based education framework
- Continuous internal assessment: 40% weightage
- End semester examination: 60% weightage
- Minimum passing requirement: 40% in external and 45% overall
- Uses the 10-point grading system
- SGPA to percentage conversion formula: (SGPA - 0.75) × 10
The 2017 scheme was implemented for students admitted from 2017-18. Key points include:
- Continuous internal assessment: 40% weightage
- End semester examination: 60% weightage
- Minimum passing requirement: 35% in external and 45% overall
- Uses the 10-point grading system
- SGPA to percentage conversion formula: (SGPA - 0.75) × 10
The 2015 scheme was implemented for students admitted between 2015-16 and 2016-17. Key points include:
- Continuous internal assessment: 25% weightage
- End semester examination: 75% weightage
- Minimum passing requirement: 35% in external and 45% overall
- Uses the 10-point grading system
- SGPA to percentage conversion formula: (SGPA - 0.75) × 10
CGPA to Percentage Conversion for VTU
The Cumulative Grade Point Average (CGPA) is the average of SGPAs of all semesters. VTU uses the same formula for converting CGPA to percentage as it does for SGPA:
For example, if your CGPA is 8.2, your percentage would be:
Percentage = (8.2 - 0.75) × 10 = 74.5%
Frequently Asked Questions
What is the minimum SGPA required to pass a semester at VTU?
To pass a semester, you need a minimum grade point of 4 (grade 'E') in each subject, which corresponds to 45% marks. There is no minimum SGPA requirement, but you must pass all subjects.
Is the SGPA to percentage conversion formula the same for all VTU schemes?
Yes, the formula (SGPA - 0.75) × 10 remains the same across all recent schemes including 2015, 2017, and 2018 schemes.
How is GPA different from SGPA at VTU?
At VTU, SGPA refers to Semester Grade Point Average (for one semester), while CGPA refers to Cumulative Grade Point Average (across all semesters).
What is considered a good SGPA at VTU?
An SGPA of 8.5 and above (77.5% and above) is generally considered excellent. An SGPA between 7.5-8.5 is very good, 6.5-7.5 is good, and 5.5-6.5 is satisfactory.
Can I improve my SGPA in VTU?
Yes, you can improve your SGPA by reappearing for subjects where you received lower grades. However, this is typically only allowed for subjects where you received an 'F' grade (failed).
How does VTU handle backlogs?
Students with backlogs (failed subjects) must clear them in subsequent semesters. VTU typically conducts supplementary examinations for students with backlogs. The maximum number of attempts may vary based on the scheme.
