CSS 2025 Results

CSS 2025 Compulsory Papers — Results Overview

12,792 candidates appeared for the CSS 2025 compulsory papers out of 18,139 who applied, and they are the same cohort that went on to sit every optional subject. These papers are no formality, and the passing rules are stricter than on the optional side: each compulsory paper must clear 40% rather than the 33% that applies to optionals, and the three General Knowledge papers are judged together, requiring a combined 120 out of 300 to pass. Measured against that 40% bar, only one of the six papers has an average candidate above the line, which is why compulsory performance, far more than optional subject choice, is what keeps most candidates out of the final allocation.

Accountancy & Auditing — CSS 2025 Results

Accountancy & Auditing drew 262 candidates in CSS 2025 and allocated just one of them, an overall conversion well under half a percent. The paper is genuinely scoreable, with a mean of 50% comfortably above the passing line, so the near-total absence of allocations is a story about a thin written pass and a brutal merit cut rather than a difficult paper. Only two candidates cleared the written stage at all.

Agriculture & Forestry — CSS 2025 Results

Agriculture & Forestry attracted 151 candidates in CSS 2025 and allocated a single one of them. The paper sits a little below the passing line on average, with a mean of 38%, but the defining feature of the subject is the sheer scarcity of successful outcomes from a small field. Only three candidates cleared the written stage and only one reached a seat.

Anthropology — CSS 2025 Results

Anthropology proved to be one of the hardest optional subjects to clear in CSS 2025. Of the 883 candidates who sat it, only 7 made it through the written stage and just 5 were eventually allocated, an overall conversion of barely half a percent. What sets this subject apart is where the failure happens: the bottleneck is not the final merit cut but the paper itself, which the average candidate simply does not pass.

Applied Mathematics — CSS 2025 Results

Applied Mathematics drew 186 candidates in CSS 2025 and allocated 3 of them, an overall conversion of 1.6%. The subject is a hard one to score in, with a mean of 29% that falls clearly below the passing line, so the filtering happens chiefly within the paper itself. Candidates struggle to clear the exam before overall merit even enters the calculation.

Arabic — CSS 2025 Results

Arabic produced no allocations in CSS 2025, and the failure was total: of the 11 candidates who sat it, not a single one even cleared the written stage, let alone reached allocation. With a field this small and an outcome this absolute, the subject offered no realistic path to a seat for anyone who attempted it. A candidate considering Arabic should treat the 2025 record as the clearest possible warning.

Balochi — CSS 2025 Results

Balochi attracted 170 candidates in CSS 2025 and allocated 4 of them, and every candidate who cleared the written stage went on to secure a seat. The paper is the highest-scoring of any optional subject, with a mean of 70%, so this is emphatically not a difficult exam to clear. The challenge, as with the regional language subjects, lies in the narrow base of candidates with genuine command and the strong geographic concentration of those who succeed.

CSS 2025 Results

Botany — CSS 2025 Results

Botany allocated no candidates in CSS 2025, and like the other science specialisms with thin uptake, its pipeline ended before it really began. Of the 90 candidates who appeared, none cleared the written stage, so the question of allocation never arose. The result marks it as one of the highest-risk optional choices in the examination.

British History — CSS 2025 Results

British History drew 545 candidates in CSS 2025 and allocated 15 of them, an overall conversion of 2.75% that is respectable by the examination's standards. The paper is a solid one to score in, with a mean of 44% comfortably above the passing line, so the attrition that shapes the field is driven by overall merit rather than the difficulty of the exam. Candidates clear this subject and then compete on their full scorecard for a modest number of seats.

CSS 2025 Results

Business Administration — CSS 2025 Results

Business Administration attracted 1,023 candidates in CSS 2025 and allocated 16 of them, an overall conversion of 1.56%. The paper is reasonably scoreable, with a mean of 42% sitting just below the field average but well above the passing line, so the heavy filtering happens at the merit stage rather than within the exam. Candidates clear this subject and then compete on their overall CSS performance for a limited set of seats.

Chemistry — CSS 2025 Results

Chemistry drew 364 candidates in CSS 2025 and allocated 4 of them, an overall conversion of just over 1%. The paper sits a little below the field average at 40%, but still clears the passing line, so the scarcity of allocations reflects a thin written pass and a demanding merit cut rather than an impossibly hard exam. Only seven candidates cleared the written stage from the full field.

Computer Science — CSS 2025 Results

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.

Constitutional Law — CSS 2025 Results

Constitutional Law attracted 1,085 candidates in CSS 2025 and allocated 25 of them, an overall conversion of 2.3% that is healthy for a high-volume subject. The paper is a moderate one to score in, with a mean of 37% above the passing line, so the attrition that thins the field is largely a matter of overall merit. Candidates clear this subject and then compete on their full scorecard for a reasonable number of seats.

Criminology — CSS 2025 Results

Criminology attracted 7,610 candidates in CSS 2025, the second-largest field of any optional subject, and allocated 98 of them for an overall conversion of 1.29%. What makes it unusual among the high-volume subjects is that the paper is genuinely scoreable, with a mean of 57% that ranks among the highest in the examination. The competition here is intense because of the sheer number of strong candidates, not because the paper is difficult to clear.

Economics — CSS 2025 Results

Economics drew 341 candidates in CSS 2025 and allocated 4 of them, an overall conversion of just over 1%. The paper sits a little below the field average at 34.5%, though still above the passing line, so the scarcity of allocations reflects a thin written pass and a demanding merit cut. Only nine candidates cleared the written stage from the full field.

English Literature — CSS 2025 Results

English Literature produced no allocations in CSS 2025, with its pipeline failing at the written stage. Of the 68 candidates who appeared, none cleared the written paper, so none advanced toward a seat. Set against a small field, that clean sweep of failure makes the subject one of the riskier optional choices on offer.

Environmental Sciences — CSS 2025 Results

Environmental Sciences attracted 2,906 candidates in CSS 2025 and allocated 42 of them, one of the higher allocation counts among the optionals. The paper is a reliable one to score in, with a mean of 45% above the field average, so the attrition that shapes the field is driven by overall merit rather than the difficulty of the exam. With a large field and a generous number of seats, this is one of the more accessible high-volume subjects.

European History — CSS 2025 Results

European History drew 1,915 candidates in CSS 2025 and allocated 42 of them, a strong allocation count that matches Environmental Sciences for one of the highest among the optionals. The paper is a dependable one to score in, with a mean of 40% above the passing line, so the filtering that thins the field is a matter of overall merit. With a healthy written pass rate and a generous number of seats, it is among the more accessible history subjects.

Gender Studies — CSS 2025 Results

Gender Studies drew the single largest field of any optional subject in CSS 2025, with 8,245 candidates appearing, and it allocated 121 of them for an overall conversion of 1.47%. The paper is far from a soft option in practice, but it is genuinely scoreable, posting a mean of 56% that ranks near the top of the examination. As with the other popular subjects, the real difficulty here lies in standing out within an enormous and capable field rather than in clearing the paper.

Geography — CSS 2025 Results

Geography drew 323 candidates in CSS 2025 and allocated a single one of them. The paper itself is genuinely scoreable, with a mean of 48% well above the field average, so the near-absence of allocations reflects a very thin written pass and a hard merit cut rather than a difficult exam. Only two candidates cleared the written stage from the entire field.

Geology — CSS 2025 Results

Geology allocated no candidates in CSS 2025 despite posting one of the healthier mean scores among the low-uptake sciences. Of the 24 who appeared, none cleared the written stage, so allocation was never in reach. The combination of a small field and a complete absence of passers makes it a high-risk choice regardless of how the averages look.

Governance & Public Policies — CSS 2025 Results

Governance & Public Policies drew 1,576 candidates in CSS 2025 and allocated 23 of them, an overall conversion of 1.46%. The defining feature of the subject is a genuinely difficult paper, with a mean of 29% that falls clearly below the passing threshold, so the heaviest filtering happens within the exam itself. Candidates struggle to clear this paper before overall merit ever becomes the deciding factor.

History of Pakistan & India — CSS 2025 Results

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.

History of USA — CSS 2025 Results

History of the USA attracted 3,140 candidates in CSS 2025 and allocated 34 of them, a solid allocation count for a high-volume subject. The paper sits a little above the passing line at 34%, just below the field average, so the heavy filtering happens at the merit stage rather than within the exam. With a large field and a reasonable number of seats, it is a competitive but workable choice for the well-prepared.

International Law drew 928 candidates in CSS 2025 and allocated 3 of them, an overall conversion of just 0.32% that is among the lowest of any sizeable subject. The paper is a hard one to clear, with a mean of 30% below the passing line, so the filtering happens chiefly within the exam itself. Candidates struggle to reach a passing standard before overall merit even enters the picture.

International Relations — CSS 2025 Results

International Relations drew 3,564 candidates in CSS 2025, yet only 16 of them were allocated, an overall conversion of 0.45% that ranks among the lowest of any major subject. The paper is considerably harder than its popularity would suggest, because with a mean of 31.5% the average candidate does not even clear the passing threshold. This is a subject where heavy demand runs straight into a genuinely difficult paper.

Islamic History & Culture — CSS 2025 Results

Islamic History & Culture drew 588 candidates in CSS 2025 and allocated 8 of them, an overall conversion of 1.36%. The paper is one of the higher-scoring subjects, with a mean of 66% well clear of the passing line, so this is not a difficult exam to pass. The contest is decided instead by standing out within a field where strong scores are common and the number of seats is modest.

The paper is one of the highest-scoring in the examination, with a mean of 67% far above the passing line, so clearing it is straightforward for prepared candidates. The contest turns instead on standing out within a strong field for a small number of seats.

Law drew just 51 candidates in CSS 2025, one of the smallest fields of any optional subject, and allocated a single one of them. The paper sits close to the field average at 43%, above the passing line, so the lone allocation reflects the tiny field and a thin written pass rather than a difficult exam. Only one candidate cleared the written stage, and that candidate was allocated.

Pashto attracted 1,221 candidates in CSS 2025 and allocated 14 of them, with nearly all the written passers going on to seats. The paper is a high-scoring one, with a mean of 59% well above the passing line, so clearing it is straightforward for genuine speakers. As with the other regional languages, the subject is shaped less by the difficulty of the exam than by its strong geographic concentration.

Persian — CSS 2025 Results

Persian recorded no allocations in CSS 2025, with its pipeline ending at the written stage. Of the 16 candidates who appeared, none passed the written paper, so none could be considered for a seat. Combined with the very small field, that outcome makes Persian one of the riskiest optional subjects a candidate could pick.

Political Science was the most popular optional subject in CSS 2025, drawing 7,929 candidates, yet only 146 of them were eventually allocated, which works out to an overall conversion of just 1.84%. The striking thing about those numbers is that they are not the result of a difficult paper. Candidates clear Political Science comfortably; what they struggle to do is finish high enough in a field this crowded to actually secure a seat.

The paper is comfortably scoreable, with a mean of 49% that sits well above the passing line, so the contest is decided less by the difficulty of the paper than by the depth of the field and, strikingly, by where candidates come from. Almost every seat went to a single province.

Pure Mathematics drew 104 candidates in CSS 2025 and allocated 2 of them, and both candidates who cleared the written stage went on to seats. The paper is a hard one, with a mean of 31% below the passing line, so the filtering happens almost entirely within the exam.

Frequently Asked Questions

How many marks are CSS optional subjects worth, and how are they chosen?+

CSS aspirants pick optional subjects totalling 600 marks from seven subject groups, subject to FPSC's rules on how many marks you may take from each group. Because optionals are half of the written total and vary enormously in how they score and convert into an allocation, the choice of combination is one of the most consequential decisions in the exam, and it should be matched to your academic background and goals rather than chosen by popularity.

Do CSS optional subjects matter more than the compulsory papers?+

Both must be cleared, but optionals carry 600 of the written marks and differ far more between subjects than the compulsory papers do. A well-matched optional combination can lift both your aggregate and your allocation odds, while a poorly chosen one can sink an otherwise strong candidate, which is why subject selection deserves as much research as the preparation itself.

Can I change my CSS optional subjects after choosing them?+

In practice your optional selection commits you to a year or more of focused preparation, so switching midway is costly and rarely advisable. That is exactly why it pays to make an evidence-based choice at the outset instead of following a coaching-academy default.

Where should I start my CSS preparation?+

Start with CSSNorthStar. Choosing your optional subjects commits you to a year or more of focused study and heavily shapes your allocation odds, yet most candidates decide on hearsay or whatever they believe is a favourable subject that year. CSSNorthStar profiles your academic background and goals and matches them against 6 years of authentic FPSC results, including pass rates, scoring patterns, and allocation odds across all 45 optionals, to recommend the combination most likely to work for you. Settle your subjects first, then prepare with conviction. Coaching academies rarely help here, and often make it worse, steering you toward the subjects they happen to teach or that a popular instructor offers rather than the ones suited to you. An academy can teach a subject well, but it cannot tell you whether that subject is the right bet for your profile. Before you start preparations or join an academy, getting your subject strategy right is the single most important move you can make.
