Enter the credits you have actually secured and this tells you whether clause 7.3 promotes you or detains you — and if you are short, by exactly how many credits.
| Promotion | Credits required | Out of | Share |
|---|---|---|---|
| 1st year → 2nd year | 20 | 40 | 50% |
| 2nd year → 3rd year | 48 | 80 | 60% |
| 3rd year → 4th year | 72 | 120 | 60% |

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.
What “secured credits” means, precisely
This is where most students get the wrong answer, so it is worth being exact.
A credit is secured only when you have passed the subject. A subject you are still carrying as a backlog contributes nothing, no matter how close you were to the pass mark. If you sat a supplementary exam and cleared it, those credits count from the moment the result is declared.
The number you want is the total credits you have passed across every semester up to that point — not the credits offered, and not the credits you attempted.
The rule this page uses
JNTUH sets promotion on cumulative credits, not on how many subjects you failed. Clause 7.3 of the R22 B.Tech regulations gives three checkpoints:
- 1st year to 2nd year — at least 20 of the 40 credits offered in I year (50%).
- 2nd year to 3rd year — at least 48 of the 80 credits offered up to II year (60%).
- 3rd year to 4th year — at least 72 of the 120 credits offered up to III year (60%).
Notice there is no checkpoint between semesters within a year. You move from I-I to I-II regardless; the credit gate applies when you move up a year.
If you come up short
Being detained is not the same as being out. It means you repeat the year alongside the next batch while continuing to clear backlogs through supplementary examinations. The credits you already hold stay with you.
The practical move, if the calculator says you are short, is to work out which backlog subjects carry the most credits and target those first. Clearing one 4-credit subject moves you further than clearing two 1.5-credit labs — and when you are three or four credits short, that choice decides the year.
One important caveat
JNTUH has relaxed these thresholds for specific academic years before, usually announced through a circular rather than a change to the regulations themselves. If a notification for your year states different numbers, that notification is what applies to you — not this page and not the base regulation.
Check the official JNTUH site, or your college examination branch, before making a decision that depends on the exact threshold.
