Enter your internal marks. This tells you the exact score you need in the semester end examination to pass — and, when it applies, that no score will be enough.

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 this is the university's rule for a theory subject; laboratories, projects and audit courses are assessed differently, so check your own subject before relying on the number.
The three conditions, and why two of them surprise people
Most students think passing means scoring 40 out of 100. Clause 7.1 actually sets three conditions that all have to hold at once:
- At least 14 of 40 in internals — 35% of the CIE.
- At least 21 of 60 in the exam — 35% of the SEE.
- At least 40 of 100 between them — 40% overall.
Two consequences follow that almost nobody states plainly.
Below 14 internals, the subject is already gone
The internal minimum is a condition in its own right, not something the exam can compensate for. A student sitting on 13 out of 40 cannot pass that subject, and a perfect 60 in the examination does not change it.
This is worth knowing in the week before the exam rather than on results day. If you are in that position, speak to your department now — the subject has to be repeated, and how that works is a question with a real answer.
Above 19 internals, the requirement stops falling
Strong internals reduce what you need in the exam, but only until you hit the exam’s own 35% floor. From 19 internals onwards the answer is 21 out of 60 and stays there.
So 38 out of 40 in internals does not let you scrape through with five marks in the exam. The floor does not care how good your internals were.
The whole rule, in one table
| Internal marks (of 40) | Needed in the exam (of 60) |
|---|---|
| Below 14 | Cannot pass, whatever the exam score |
| 14 | 26 |
| 15 | 25 |
| 16 | 24 |
| 17 | 23 |
| 18 | 22 |
| 19 and above | 21 |
Aiming higher than a pass
The calculator also shows what each grade would cost from where you are, using the R22 grade bands. The same two conditions apply, so a grade that would need more than 60 in the exam is marked out of reach rather than shown as a number you cannot score.
That matters more than it sounds. Deciding in week two that an A is gone and a B+ is comfortably available is a better use of a semester than discovering it in the exam hall.
What this does not cover
These are the rules for a theory subject. Laboratories, projects, internships and audit courses are assessed on their own patterns, and the split is not always 40/60. Check your subject before planning around this number.
And as always: your college’s examination branch is the authority on your marks. This calculates from the published regulation, not from your record.
