JNTUH Grading System
What Is JNTUH and How Does Its Grading System Work?
JNTUH is a public state university established on 2 October 1972 under the Government of Telangana. Located on an 89-acre campus in Kukatpally, Hyderabad, it affiliates 423+ engineering and technical colleges across Telangana – making it one of India’s largest technical affiliating universities. One important distinction: JNTU split into four separate universities in 2008.
JNTUH covers Hyderabad and Telangana. JNTUK covers Kakinada in Andhra Pradesh. JNTUA covers Anantapur. Students must confirm their affiliating university before applying grading rules JNTUH regulations apply only to colleges affiliated to the Hyderabad campus. Results and grade norms for JNTUK-affiliated colleges follow JNTUK’s own regulations.
JNTUH uses a 10-point Choice Based Credit System (CBCS) where seven letter grades (O, A+, A, B+, B, C, F) map to grade points between 0 and 10. Students need a minimum C grade (5 grade points) to pass any subject. CGPA converts to percentage using the formula (CGPA – 0.5) × 10, as stated in JNTUH B.Tech Academic Regulations (R16/R18/R22), Clause 11.2. Degree classification ranges from First Class with Distinction (70% and above) to Pass Class (50%-60%)
What Letter Grades Does JNTUH Assign?
JNTUH assigns seven letter grades under its 10-point absolute grading system: O, A+, A, B+, B, C, and F. Each grade maps to a fixed percentage range earned in the combined Continuous Internal Evaluation (CIE) and Semester End Examination (SEE). A student scoring 90% or above earns an O (Outstanding) grade worth 10 grade points, while anything below 40% results in an F (Fail) with 0 grade points.
Here’s the complete JNTUH grading scale under R22 regulations:
Letter Grade | Grade Description | Marks Range | Grade Points |
O | Outstanding | 90% – 100% | 10 |
A+ | Excellent | 80% – 89% | 9 |
A | Very Good | 70% – 79% | 8 |
B+ | Good | 60% – 69% | 7 |
B | Average | 50% – 59% | 6 |
C | Pass | 40% – 49% | 5 |
F | Fail | Below 40% | 0 |
Ab | Absent | – | 0 |
The grading scale follows the UGC and AICTE guidelines introduced under the Choice Based Credit System reforms of 2015. Mandatory or non-credit courses receive no letter grade or marks – only a Satisfactory (S) or Unsatisfactory (U) designation. Understanding what each grade is worth in grade points is the foundation for calculating SGPA, which the next section covers step by step.
What Is the Passing Criteria in JNTUH?
A student passes a subject in JNTUH by securing a C grade or higher, which means a minimum of 5 grade points. A student who earns an F grade in any subject is required to reappear as a supplementary student in the next Semester End Examination for that subject.
Students must also pass both components separately – CIE and SEE – according to the minimum marks prescribed in the regulations. An F grade carries 0 grade points, which means it pulls SGPA down significantly when included in the calculation. Failed subjects stay in the CGPA calculation until the student clears them in a supplementary exam, at which point the new passing grade replaces the F in subsequent computations.
For degree award, a student must pass every subject in the program and maintain a CGPA of 5.00 or above across all semesters. This 5.00 threshold is not the same as getting a 50% percentage – because the CGPA-to-percentage conversion formula adjusts for JNTUH’s grading floor. SGPA is the semester-level version of this calculation, which the next section explains.
How Is SGPA Calculated in JNTUH?
JNTUH calculates SGPA (Semester Grade Point Average) by dividing the sum of credit points earned across all subjects in a semester by the total credits registered for that semester. Credit points for each subject equal the subject’s credits multiplied by the grade points earned.
The formula is:
SGPA = Σ(Credits × Grade Points) / Total Credits
Here’s a worked example for a student in Semester 3 under R22:
Subject | Credits (C) | Grade | Grade Points (GP) | Credit Points (C × GP) |
Data Structures | 4 | A+ | 9 | 36 |
Digital Electronics | 3 | A | 8 | 24 |
Mathematics III | 4 | B+ | 7 | 28 |
Environmental Science | 3 | B | 6 | 18 |
DS Lab | 1.5 | O | 10 | 15 |
DE Lab | 1.5 | A+ | 9 | 13.5 |
Total | 17 | 134.5 |
SGPA = 134.5 ÷ 17 = 7.91
A subject where the student earns an F grade contributes 0 credit points but still counts in the total credits denominator – this is why one failed subject can drop SGPA sharply. SGPA is calculated and reported at the end of every semester from Semester 1 onwards. Once you have SGPA for all semesters, you can calculate CGPA – covered next.
How Is CGPA Calculated in JNTUH?
JNTUH calculates CGPA (Cumulative Grade Point Average) as the weighted average of SGPA values across all semesters, where each semester’s SGPA is weighted by its total credits. CGPA calculation starts from the second semester (1st year, 2nd semester) onwards.
The formula is:
CGPA = Σ(SGPA × Semester Credits) / Total Credits Across All Semesters
Here’s a condensed example for a student completing 4 years of B.Tech (8 semesters) under R22, which requires 192 total credits:
Semester | SGPA | Credits | SGPA × Credits |
Sem 1 | 7.80 | 24 | 187.2 |
Sem 2 | 8.10 | 24 | 194.4 |
Sem 3 | 7.91 | 24 | 189.84 |
Sem 4 | 8.50 | 24 | 204 |
Sem 5 | 8.20 | 24 | 196.8 |
Sem 6 | 7.60 | 24 | 182.4 |
Sem 7 | 8.00 | 24 | 192 |
Sem 8 | 8.30 | 24 | 199.2 |
Total | 192 | 1545.84 |
CGPA = 1545.84 ÷ 192 = 8.05
Under the new R25 regulations (applicable from 2025-26 admissions), students complete 164 credits but only the best 160 count toward the final CGPA – allowing up to 4 credits worth of low-grade or failed subjects to be dropped. This rule does not apply to labs, seminars, internships, or project subjects. Once you have your CGPA, the next step is converting it to a percentage for job applications, higher studies, or government forms.
How Do You Convert JNTUH CGPA to Percentage?
JNTUH converts CGPA to percentage using the official formula: Percentage = (CGPA – 0.5) × 10. This formula is defined in JNTUH B.Tech Academic Regulations (R16/R18/R22), Clause 11.2, and applies across all affiliated colleges under JNTUH.
Here’s the conversion table for common CGPA values:
CGPA | Formula Applied | Percentage |
10.0 | (10.0 – 0.5) × 10 | 95% |
9.0 | (9.0 – 0.5) × 10 | 85% |
8.5 | (8.5 – 0.5) × 10 | 80% |
8.05 | (8.05 – 0.5) × 10 | 75.5% |
7.5 | (7.5 – 0.5) × 10 | 70% |
7.0 | (7.0 – 0.5) × 10 | 65% |
6.5 | (6.5 – 0.5) × 10 | 60% |
6.0 | (6.0 – 0.5) × 10 | 55% |
5.5 | (5.5 – 0.5) × 10 | 50% |
5.0 | (5.0 – 0.5) × 10 | 45% |
Note that JNTUK (Kakinada) uses a different formula – (CGPA – 0.75) × 10 – so the two universities’ outputs are not directly interchangeable on forms that ask for a percentage. Always specify “JNTUH” alongside the converted percentage when submitting to employers or graduate programs. Most campus placement forms at companies like TCS and Infosys request this percentage conversion. The percentage also determines which degree classification you receive at graduation.
What Are the Degree Classifications in JNTUH?
JNTUH awards B.Tech degree classifications based on the final CGPA and its converted percentage. First Class with Distinction requires 70% or above (CGPA 7.5+), First Class requires 60%-69.99% (CGPA 6.5-7.49), and Second Class covers 50%-59.99% (CGPA 5.5-6.49).
The full classification table:
Classification | Percentage Range | Equivalent CGPA |
First Class with Distinction | 70% and above | 7.5 and above |
First Class | 60% – 69.99% | 6.5 – 7.49 |
Second Class | 50% – 59.99% | 5.5 – 6.49 |
Pass Class | 45% – 49.99% | 5.0 – 5.49 |
To earn First Class with Distinction, a student must have no backlogs at the time of degree award, in addition to meeting the CGPA threshold. Students who cleared backlogs through supplementary exams may still qualify, but the regulations specify that the “no arrear” condition applies at the time of final degree award – not throughout the program. The CGPA required for distinction in most placement-level requirements is 7.5 or above, which maps to 70% under the (CGPA – 0.5) × 10 formula.
What Credits Does JNTUH Require to Complete B.Tech?
JNTUH B.Tech students under R22 must complete 192 total credits across 8 semesters (24 credits per semester) to be eligible for degree award. Under the newer R25 regulations (from 2025-26 batch), students complete 164 credits with the best 160 counting toward the final CGPA.
Each semester is structured around 24 credits covering theory subjects, laboratory courses, mini-projects, and mandatory non-credit courses. Non-credit mandatory courses do not count in CGPA calculations – they appear on the transcript with only S (Satisfactory) or U (Unsatisfactory) notation. The 192-credit requirement under R22 makes JNTUH’s total credit load one of the higher requirements among affiliated technical universities in Telangana.
The R25 four-credit drop provision targets theory subjects only – a student cannot drop a lab, seminar, internship, or project from the CGPA count. This change reduces pressure from individual subject failures while keeping practical and project performance fully accountable. Students admitted before 2025-26 continue under their original regulations (R22, R18, or R16) throughout their program.
How Do Backlogs Affect JNTUH CGPA?
Backlogs in JNTUH directly lower CGPA because failed subjects count as 0 grade points in all SGPA and CGPA calculations until the student clears them. Every backlog reduces the numerator in the SGPA formula while the credits denominator stays unchanged.
For example: a student with 17 credits in a semester who fails one 4-credit subject with an F grade loses 40 credit points minimum (4 credits × 10 grade points = 40 points lost versus getting an O). If that same student scored an average B+ (7 grade points) across the other 13 credits, the SGPA would fall from approximately 7.0 to around 4.7 – below the passing threshold of 5.0 for that semester.
After clearing a backlog in a supplementary exam, the new grade replaces the F in subsequent calculations. However, the grade earned in a supplementary exam is typically capped depending on the regulation – students should check the specific clause in their batch’s regulation document (R22 Clause 9.10 or equivalent). The CGPA impact of cleared backlogs improves going forward but does not retroactively change previously calculated SGPAs. Under R25’s four-credit drop rule, students admitted from 2025-26 can exclude one backlog subject (up to 4 credits) from CGPA entirely, provided it’s a theory course.
How Does JNTUH Internal and External Marking Work?
JNTUH evaluates each theory subject through two components: Continuous Internal Evaluation (CIE) worth 30 marks and the Semester End Examination (SEE) worth 70 marks, totaling 100 marks per subject. Both components together determine the letter grade awarded.
CIE includes mid-term examinations, assignments, and lab performance where applicable. Students must secure a minimum in each component separately – the combined percentage of both CIE and SEE determines the final letter grade from the JNTUH grading scale. Lab subjects follow a different split (internal practical record + external lab exam), with grades awarded on the same 10-point scale.
For students aiming at an O grade (90%+), they need a combined CIE + SEE score of 90 marks out of 100 – meaning consistent internal performance cannot substitute for a weak semester end exam. This two-component system means SGPA calculations for JNTUH results portals and JNTUH CGPA calculators for R22 and R18 incorporate both marking streams into the final grade assigned.
What Changed in JNTUH R25 Regulations?
JNTUH R25 regulations, approved for students admitted from the 2025-26 academic year in non-autonomous affiliated colleges, introduced the four-credit drop rule and adjusted the total program credits from 192 (R22) to 164 credits, with 160 counting toward CGPA.
The most significant change under R25 is the credit exclusion provision. Students completing 164 credits can have their four lowest-credit theory subject grades excluded from CGPA. This provision specifically targets students who fail or score low in one subject, reducing the severe CGPA penalty previously applied under R22. Autonomous colleges were encouraged to adopt R25 as a reference framework but retain the right to modify specifics.
The grading scale itself (O through F with 10-0 grade points) and the CGPA-to-percentage conversion formula (CGPA – 0.5) × 10 remain unchanged under R25. Students already enrolled under R22, R18, or R16 continue under those regulations for the remainder of their program – regulation changes apply only to new admissions. Batch-specific changes like these affect SGPA calculator inputs, JNTUH result interpretations, and degree classification thresholds on final mark sheets.
FAQ
What is the minimum CGPA required to pass JNTUH B.Tech?
A student must maintain a CGPA of 5.00 or above and must have passed all registered subjects to be eligible for the B.Tech degree award. A CGPA below 5.00 at the time of degree completion means the student has not met the minimum aggregate performance standard.
What is 8.0 CGPA in percentage for JNTUH?
An 8.0 CGPA equals (8.0 – 0.5) × 10 = 75% under the official JNTUH formula. This falls in the First Class with Distinction range since it crosses the 70% threshold.
Does JNTUH multiply CGPA by 10 to get percentage?
No. JNTUH uses the formula (CGPA – 0.5) × 10, not a simple multiplication by 10. Direct multiplication overestimates the percentage because it does not account for the grade point floor of the 10-point scale.
What is the difference between SGPA and CGPA in JNTUH?
SGPA is the grade point average for a single semester. CGPA is the weighted cumulative average of all SGPAs across all completed semesters, weighted by semester credits.
Can a student with backlogs get First Class with Distinction in JNTUH?
A student who clears all backlogs before the degree award and meets the CGPA threshold of 7.5 (70%) may qualify for First Class with Distinction. The regulations require no pending arrears at the time of degree, not that the student was arrear-free throughout the program.
How many credits does JNTUH R22 B.Tech require?
JNTUH R22 requires 192 total credits across 8 semesters (24 credits per semester) for the B.Tech degree award.
What does the Ab (Absent) grade mean in JNTUH?
Ab means the student was absent for the Semester End Examination. It carries 0 grade points and is treated similarly to an F grade in SGPA calculations, requiring the student to appear as a supplementary candidate.
