NORCET negative marking: when to guess and when to skip

In NORCET, a correct answer earns 1 mark, a wrong answer costs ⅓ of a mark, and a question you leave blank scores 0. That small fraction changes how you should approach the questions you're unsure of — and once you see the arithmetic, the right rule is simple.

Three wrong answers cancel one right answer

Lose ⅓ three times and you've lost a full mark. That's why a paper full of hopeful guesses can score lower than a paper with fewer attempts.

A blind guess is worth nothing — on average

With four options and no idea which is right, you have a 1-in-4 chance of +1 and a 3-in-4 chance of −⅓. On average that's (¼ × 1) − (¾ × ⅓) = 0. You add risk, not marks.

Eliminate one option and the maths flips

If you're sure one option is wrong, you're choosing from three: (⅓ × 1) − (⅔ × ⅓) = +1/9 of a mark on average. Small, but positive — and across ten such questions it adds up to about a mark.

Eliminate two and guessing is clearly worth it

Choosing between two: (½ × 1) − (½ × ⅓) = +⅓ of a mark on average.

So the rule is

1. Know it → answer.
2. Can rule out at least one option with confidence → answer your best choice.
3. No idea at all → skip it, and come back if time allows.

Two cautions

First, these are averages over many questions — any single guess can still go wrong. Second, "confident elimination" means real knowledge, not a hunch. If your eliminations are often wrong, your guesses will lose marks; your mock results will tell you.

Watch for rushing

The most expensive mistakes are often not guesses at all — they're questions answered too fast to be read properly. Nursing Vidyarthi flags topics where you answer much faster than expected and get it wrong, so you can slow down where it matters.

Practise the rule, don't just know it

Take a mock with NORCET marking, then look at how many marks negative marking cost you and in which subjects. That's where to work next. For the full structure of both stages, see the NORCET exam pattern.
