Constitutional Law
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.
Score Distribution
The mean of 37% clears the passing line by 4 points, and with the median of 39% sitting above it the distribution leans slightly to the left. A standard deviation of 13 points, fairly contained, places a candidate one deviation below the mean at 24%, into failing territory, which marks this as a moderate-risk paper. The average candidate passes, but the margin above the threshold is narrow enough that a weaker showing drops below it. Preparation that lifts a candidate a few points clear of the line is therefore directly valuable here. Statistically the median two points above the mean marks a mild left skew, where a minority of low scripts drags the average down, so the typical candidate clears the line by a touch more than the bare mean suggests.
Provincial Breakdown
Punjab took 12 of the 25 seats, just under half, with KPK on 7 and Sindh Rural, Ex-FATA and Azad Kashmir sharing the rest. The spread is reasonably broad, with KPK's strong showing standing out, and it tracks the geography of legal education and CSS preparation across the provinces.
Gender Distribution
Women took 11 of the 25 seats, a 44% share that sits below the CSS-wide rate of 50.7%. The under-representation is modest but real, indicating that male candidates converted at a somewhat higher rate once they cleared the written stage in this subject.
Subject vs CSS Average
Constitutional Law's mean of 37% trails the CSS optional-subject average of 43.5% by 6.5 points, placing it a little below the field in scoring terms. The gap means clearing the paper takes solid preparation rather than coming easily, but the subject's strong written pass rate and high conversion to allocation make it more rewarding than the modest mean alone would suggest. With 25 seats, it is among the more accessible law options for well-prepared candidates.
Candidate Pipeline
Of the 1,085 who appeared, 41 passed the written stage at a 3.78% pass rate, and 25 of those were allocated. With a mean of 37% above the 33% threshold, the subject is not the principal bottleneck; candidates clear it and then lose around 40% of their number at the merit cut. The relatively high conversion of written passers into seats makes this one of the more rewarding law subjects for those who clear the paper.
Constitutional Law is a solid choice for candidates with a genuine grasp of constitutional principles who can argue them clearly under exam conditions. Its healthy allocation count and good conversion of written passers make it one of the more rewarding law subjects, even with a below-average mean. The slightly lower female conversion is worth noting, but the broader picture is of an accessible, well-rewarded option for the well-prepared.
Constitutional Law candidates averaged 37.0% of the available marks, in line with fellow Group-6 subjects Law (43.0%) and Philosophy (31.0%).

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.
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.
