Understanding the grading and evaluation process is essential for every JNTUH (Jawaharlal Nehru Technological University Hyderabad) B.Tech student, especially under the R16 regulation. This guide covers everything you need to know about the JNTUH R16 grading system, SGPA, CGPA, and the final percentage calculation.
JNTUH Grading Procedure for R16 Regulation
In the JNTUH R16 B.Tech curriculum, marks are awarded for various academic activities such as:
- Theory subjects
- Laboratory/Practicals
- Seminars
- UG Mini Projects
- UG Major Projects
The total marks (Continuous Internal Evaluation + Semester End Examination) are converted into letter grades and grade points using a 10-point absolute grading system in line with UGC/AICTE guidelines.
JNTUH R16 Letter Grades and Grade Points
| Percentage Range | Letter Grade | Grade Point |
|---|---|---|
| ≥ 90% | O (Outstanding) | 10 |
| 80% – < 90% | A+ (Excellent) | 9 |
| 70% – < 80% | A (Very Good) | 8 |
| 60% – < 70% | B+ (Good) | 7 |
| 50% – < 60% | B (Average) | 6 |
| 40% – < 50% | C (Pass) | 5 |
| < 40% | F (Fail) | 0 |
| Absent | Ab | 0 |
- A student must earn at least a ‘C’ grade (GP ≥ 5) in each subject to pass.
- If a student scores an ‘F’ grade, they must reappear in the next supplementary exam.
- For absent students, the ‘Ab’ grade is awarded and treated as a failure.
How to Calculate SGPA (Semester Grade Point Average)
SGPA is the average performance of a student in a semester and is calculated using the formula:
SGPA = (Σ Ci × Gi) / Σ Ci
Where:
- Ci = Credits of the i-th subject
- Gi = Grade points of the i-th subject
- Σ Ci = Total credits for all subjects in the semester
- Σ Ci × Gi = Total credit points earned
Example of SGPA Calculation
| Subject | Credits | Grade | GP | Credit Points (CP) |
|---|---|---|---|---|
| Course 1 | 4 | A | 8 | 32 |
| Course 2 | 4 | O | 10 | 40 |
| Course 3 | 4 | C | 5 | 20 |
| Course 4 | 3 | B | 6 | 18 |
| Course 5 | 3 | A+ | 9 | 27 |
| Course 6 | 3 | C | 5 | 15 |
SGPA = 152 / 21 = 7.23
How to Calculate CGPA (Cumulative Grade Point Average)
CGPA reflects a student’s overall academic performance across all semesters. It is calculated as:
CGPA = (Σ Cj × Gj) / Σ Cj
Where:
- Cj = Credits of the j-th subject across all semesters
- Gj = Grade points earned in the j-th subject
- Σ Cj = Total credits across semesters
- Σ Cj × Gj = Total cumulative credit points
Example of CGPA Calculation
| Semester | Credits | SGPA | Credit Points |
|---|---|---|---|
| I | 24 | 7 | 168 |
| II | 24 | 6 | 144 |
| III | 24 | 6.5 | 156 |
| IV | 24 | 6 | 144 |
| V | 24 | 7.5 | 180 |
| VI | 24 | 8 | 192 |
| VII | 24 | 8.5 | 204 |
| VIII | 24 | 8 | 192 |
CGPA = 1380 / 192 = 7.18
How to Convert CGPA to Percentage – JNTUH R16
To convert your final CGPA to percentage, use the following formula:
Percentage = (CGPA – 0.5) × 10
Example:
If your CGPA is 7.18, then:
Percentage = (7.18 – 0.5) × 10 = 66.8%
JNTUH Passing Criteria for R16 Regulation
- A student must secure minimum grade point of 5 (C grade) in each subject to pass.
- For passing the B.Tech degree, a student must have a CGPA ≥ 5.00.
- Grade cards are issued after every semester showing grades, SGPA, and CGPA.
- Mandatory courses are excluded from SGPA/CGPA calculations.
- Performance in failed subjects is included only after passing in reappear exams.
Final Notes
Understanding how SGPA, CGPA, and percentage are calculated is crucial for planning your academic progress in JNTUH under the R16 regulation. Make sure to aim for consistency across semesters to maintain a high CGPA and ensure degree eligibility.
Stay updated with university notifications and syllabus changes and always check your results and grade sheets carefully.
