JNTUH published R25 academic regulations for B.Tech, applying from the 2025–26 intake. Most of the internet — including, until today, this site — is still running on R22.
Two of the changes are not cosmetic. If you are an R25 student using an R22 calculator, you are being told things that are wrong about your own degree.
The two changes that actually matter
1. Promotion was rewritten, and one gate was abolished
R22 clause 7.3 set fixed credit thresholds: 20 of 40 to enter second year, 48 of 80 to enter third year, 72 of 120 to enter fourth year.
R25 clause 14.0 does something different. It asks for 25% of the total credits studied up to that point — a percentage, not a fixed pair — and it applies that at two gates only.
The third-year-to-fourth-year credit requirement is gone. R25 asks only for a regular course of study and the attendance requirement to move into fourth year.
That is a large difference in the student’s favour, and an R22 calculator will tell an R25 student they are detained when they are not.
These figures are for R25, which applies from the 2025–26 intake. If you were admitted before that you are under R22 or earlier, where the promotion and pass rules are different — use the R22 pages instead.
| Promotion | Requirement | Of what |
|---|---|---|
| 1st year → 2nd year | 25% of the credits | the total credits up to first year second semester |
| 2nd year → 3rd year | 25% of the credits | the total credits up to second year second semester |
| 3rd year → 4th year | No credit requirement | no credit requirement in R25 — a regular course of study and the attendance requirement are all clause 14.0 asks for |
Source: JNTUH R25 B.Tech Academic Regulations, V2 (official PDF). Clause 14.0 (Promotion Rules) of the R25 B.Tech Academic Regulations. Credits count from all relevant regular and supplementary examinations, whether or not the student sat them. Checked 23 August 2026.
Two things this cannot tell you. Credits count only once you have secured them, so a subject you are still carrying as a backlog does not count until you clear it. And universities have relaxed these thresholds for particular academic years before — if a circular for your year says otherwise, the circular wins, not this page.
2. There is no separate minimum for internal marks
This is the one that worries me most, because the wrong answer is the frightening one.
Under R22, a pass needed three things: 35% of the internals (14 of 40), 35% of the semester end exam (21 of 60), and 40% overall. Fall below 14 internally and the subject was lost whatever you scored in the exam.
R25 clause 8.1 sets only two conditions — 35% of the SEE (21 of 60) and 40% of the two taken together (40 of 100). There is no standalone internal minimum.
So an R25 student with weak internals who is told by an R22 tool that their subject is already lost is being told something the regulation does not say.
| Grade | Total needed | Exam marks needed |
|---|
Source: JNTUH R25 B.Tech Academic Regulations, V2 (official PDF) . Clauses 9.1 and 8.1 of the R25 B.Tech Academic Regulations: 40 CIE and 60 SEE, with a pass needing 35% of the SEE (21 of 60) and 40% of the two taken together (40 of 100). Checked 23 August 2026.
Two things worth knowing before you plan around this. The exam minimum is a floor that does not move — strong internals reduce what you need only until they hit it, never below it. And note what this regulation does not say: it sets no separate minimum for the internal marks on their own, so low internals here do not end the subject the way they would at a university that sets one. Only the exam minimum and the combined total apply.
What did not change
The conversion formula is the same — (Final CGPA − 0.5) × 10 — but the clause number is not. It moved from R22 clause 11.2 to R25 clause 19.1, and the grade table moved to clause 10.3. If you are quoting a clause on an application or an appeal, quote the one for your own regulation.
Source: JNTUH R25 B.Tech Academic Regulations, V2 (official PDF) . Quoted from clause 19.1 of the R25 B.Tech Academic Regulations. The formula is unchanged from R22, but the clause number is not — it moved from 11.2 to 19.1. Checked 23 August 2026. Always confirm against your own marks memo before using this on an application.
| Grade | Grade points | Marks range |
|---|---|---|
| O | 10 | 90% and above (Outstanding) |
| A+ | 9 | 80% to below 90% (Excellent) |
| A | 8 | 70% to below 80% (Very Good) |
| B+ | 7 | 60% to below 70% (Good) |
| B | 6 | 50% to below 60% (Average) |
| C | 5 | 40% to below 50% (Pass) |
| F | 0 | Below 40% (Fail) |
| Ab | 0 | Absent |
Attendance is unchanged too: 75% in aggregate, condonation between 65% and 75% on genuine and valid grounds, and nothing below 65% condoned in any case. That is clauses 7.1, 7.2 and 7.5 in R25.
Source: JNTUH R25 B.Tech Academic Regulations, V2 (official PDF) . Clauses 7.1, 7.2 and 7.5 of the R25 B.Tech Academic Regulations. Unchanged from R22: 75% in aggregate to sit the semester end examinations, a shortage of up to 10% (65% and above, below 75%) condonable by the college academic committee on genuine and valid grounds, and below 65% condoned in no case. Checked 23 August 2026.
Condonation is permission, not a right — where a university offers it at all, it is granted on stated grounds, usually with a fee and an application through your college. Treat the middle band as “ask immediately”, not as “you are fine”.
The eight-year clock
R25 clause 3.1 states it plainly: the B.Tech programme must be completed in a minimum of four academic years and a maximum of eight, counted from the commencement of first year first semester, “failing which student shall forfeit seat in B.Tech. course”. Lateral entry students get six.
The degree itself needs 160 credits out of 164.
Almost nobody thinks about this clause until it is close, which is exactly why it is worth knowing early.
R22 or R25 — common questions
Which regulation am I under?
Your regulation is set by the year you were admitted, not the year you are currently in. Admitted in 2025-26 or later: R25. Admitted 2022-23 to 2024-25: R22. Earlier than that: R18 or R16. It is printed on your marks memo and in your college’s academic handbook — check there rather than guessing, because every number on this page depends on it.
Does R25 replace R22 for everyone?
No. R25 applies from the 2025-26 intake onward. Students already under R22 stay under R22, and clause 22.4 of R25 is explicit that a student who failed a course under one regulation has to pass it under that same regulation. The two run side by side for the next few years.
Is 8.4 CGPA still 79% under R25?
Yes. The formula is identical — (8.4 − 0.5) × 10 = 79%. Only the clause number changed, from 11.2 to 19.1. If you are citing it somewhere formal, cite 19.1.
Do I still need 72 credits to enter fourth year?
Not under R25. That requirement existed in R22 clause 7.3 and does not appear in R25 clause 14.0, which asks only for a regular course of study and the attendance requirement for that transition. Under R22 it still applies.
Can low internal marks fail me under R25?
Not on their own. R25 clause 8.1 sets a 35% minimum on the semester end examination and a 40% minimum on the combined total, and nothing else. Weak internals raise what the exam has to deliver, but they do not close the subject the way R22’s 14-of-40 rule could.
Where this comes from
Every figure here was read from JNTUH’s own R25 B.Tech Academic Regulations (V2), cross-checked against the V1 bulletin and the copy linked from jntuh.ac.in/rules-and-regulations. All three agree on every value above.
No figure on this page came from a coaching site, a forum thread or another calculator. If you find a discrepancy against your own copy of the regulation, tell me — on this subject one wrong number is worse than no page at all.
R22 calculators
If you are under R22, these are the right ones:
- JNTUH promotion calculator (R22) — the 20/40, 48/80, 72/120 thresholds
- JNTUH pass marks calculator (R22) — including the 14-of-40 internal minimum
- CGPA to percentage · full conversion table
