How the 40% Qualifying Bar Actually Works

Per paper, not overall

In CET Graduate Level and in School Lecturer 1st Grade, the qualifying percentage is checked against each paper on its own. A strong subject paper does not carry a weak GK paper. This is the most common misunderstanding we hear, and it is why a candidate can score well overall and still not qualify.

RAS Pre is different, and the difference matters: it has no fixed qualifying percentage at all. It is a competitive cut-off, set after the exam by the number of vacancies and by how everyone performed. The 2023 cut-off sat near 42%. We hold you to that number rather than inventing a bar, because a bar you can plan against has to be a real one.

Negative marking is applied first

The bar is checked against your net score, after deductions. With one-third of a mark taken for a wrong answer, twelve wrong guesses cancel four correct answers outright. A candidate who answers everything and gets 45% of them right does not score 45%.

Work it through on a 150-question paper. Answer all 150 and get 68 right: 82 wrong answers take back roughly 27 marks. Answer only the 100 you know something about and get 62 right: fewer marks gained, far fewer given back, and a higher net score. The second candidate qualifies and the first does not.

What it means in the exam hall

The question is never "do I know this?" but "do I know this well enough to beat the deduction?". Below roughly 34% confidence on a four-option question, guessing costs more than it earns; above it, guessing pays. That threshold is the whole strategy, and it is worth settling before the day rather than deriving under a clock.
