Computer Science drew 177 candidates in CSS 2025 and allocated 2 of them, an overall conversion of just over 1%. The paper is a hard one to clear, with a mean of 31.5% falling below the passing line, so the filtering happens largely within the exam itself. Candidates struggle to reach a passing standard before overall merit becomes a factor.
Of the 177 who appeared, 4 passed the written stage and 2 of those were allocated. Because the mean of 31.5% sits below the 33% threshold, the paper itself is the dominant bottleneck, with most candidates failing it rather than being filtered out on merit. The drop from 4 passers to 2 allocations applied a second cut at the merit stage, but the heavier losses came inside the paper.
At 31.5% of the 200 available marks the mean falls just under the passing line, and the median, close behind at 32.5% of max, sits near it, indicating a roughly balanced distribution. A standard deviation of 29 marks, around 14.5 percentage points, is wide, placing a candidate one deviation below the mean at 17% and one above at 46%, so the band of typical performance straddles the threshold. This is a high-risk paper to score in, since the average candidate falls short and only those clearly above the mean cross into passing territory. Strong technical preparation that lifts a candidate above the line is decisive here.
The two allocations went to Balochistan and Punjab, one each. With only two seats there is no distribution to speak of, just the record of two individual outcomes from different provinces.
The two seats split between one woman and one man, an even outcome in a sample of two. No gender pattern can be drawn from so small a result.
Computer Science's mean of 31.5% trails the CSS optional-subject average of 43.5% by 12 points, placing it among the harder-scoring papers despite the strong technical backgrounds many of its candidates bring. The expectation that a computing degree makes this an easy pick is not borne out by the figures. Because the subject sits well below the field average, clearing 33% already lifts a candidate above most competitors, but with only 2 seats the margin is razor-thin. The realistic aim is to score well above the mean rather than to scrape over the line.
Computer Science is a high-risk choice that its technical framing can disguise, with a sub-threshold mean and only two allocations from a field of 177. It suits candidates with genuine depth in the discipline who can write precise, complete answers under pressure, not those assuming a programming background will carry the paper. This is a subject to attempt from real strength, given how few cleared it in 2025.
