History of Pakistan & India attracted 2,094 candidates in CSS 2025 and allocated only 12 of them, an overall conversion of 0.57% that places it among the harder subjects to convert. The paper sits right on the edge of difficulty, with a mean of 31% that falls just short of the passing line even as the median lands exactly on it. That fine balance means the subject filters heavily at the paper itself before merit is even considered.
At 31% the mean falls two points under the passing threshold, yet the median of exactly 33% tells a subtler story, since it means half the candidates reached the line even though the average sits below it, with a tail of low scorers dragging the mean down. A standard deviation of 12 points places a candidate one deviation below the mean at 19% and one above at 43%, so the band of typical performance straddles the threshold. This is a high-risk paper to score in, because the average candidate falls just short and only those at or above the median cross into passing territory. The narrow gap between mean and threshold makes preparation that lifts a candidate a few points genuinely decisive here. This is the clearest case of why the skew matters: with the mean two points under the line but the median exactly on it, the left skew created by the low-scoring tail is the entire difference between an average that fails and a middle candidate who scrapes through.
Punjab took 8 of the 12 seats, two-thirds of the total, with KPK and Sindh Rural each securing 2 and the remaining provinces shut out entirely. In a field this small the distribution is inevitably coarse, but the concentration in Punjab is consistent with the broader pattern of where CSS preparation is densest.
The 12 seats split evenly, with women taking 6 and men 6, a 50% female share that effectively matches the CSS-wide rate of 50.7%. With a sample this small the parity is more illustrative than statistically firm, but it indicates no meaningful difference in conversion between men and women in this subject.
History of Pakistan & India's mean of 31% trails the CSS optional-subject average of 43.5% by 12.5 points, marking it as one of the tougher papers to score in despite its familiar subject matter. Many candidates choose it expecting that broad general knowledge will carry them, and the figures suggest that expectation is misplaced. Because the subject sits below the field average, simply clearing 33% already lifts a candidate above most of the pack, but with only 12 seats against more than two thousand applicants, a bare pass is a long way from a secure outcome. The sensible target is to score clearly above the median rather than to hover at the line.
Of the 2,094 who appeared, just 33 passed the written stage at a 1.58% pass rate, and 12 of those were allocated. Because the mean of 31% sits below the 33% threshold, the dominant bottleneck is the paper itself, with the bulk of candidates failing to clear it before overall merit comes into play. The subsequent drop from 33 passers to 12 allocations adds a second filter at the merit stage, but the heaviest losses happen inside the paper.
History of Pakistan & India is a demanding choice that its accessibility tends to disguise, combining a sub-threshold mean with a very low allocation count. It rewards candidates with disciplined, analytical command of the material who can write a few points above the median under pressure, rather than those relying on general familiarity with the subject. Given how finely the paper sits against the passing line, the margin between preparation and its absence is unusually decisive here.
