Physics
Physics drew 292 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%, though above the passing line, so the scarcity of allocations reflects a thin written pass and a hard merit cut. Only six candidates cleared the written stage from the full field.
Gender Distribution
Of the four allocated candidates, one was a woman and three were men, a 25% female share in a sample too small to generalise from. The figure simply records the outcome for four individuals.
Subject vs CSS Average
Physics' mean of 40% trails the CSS optional-subject average of 43.5% by 3.5 points, placing it modestly below the field. The gap is minor and overshadowed by the subject's thin written pass and four allocations from 292 candidates. For a prospective candidate, the near-average mean matters far less than the reality that very few cleared the paper to a competitive standard, amid an unusually wide scoring spread.
Candidate Pipeline
Of the 292 who appeared, 6 passed the written stage and 4 of those were allocated. With a mean of 40% above the 33% threshold, the paper is not the principal barrier, yet the low written pass count shows how few candidates reached a passing standard in this technical subject. The good conversion of written passers into seats suggests the merit stage was relatively forgiving for the rare candidates who cleared the paper.
Score Distribution
At 40% of the 200 available marks the mean clears the passing line, and the median, close behind at 42% of max, sits near it, suggesting a balanced distribution. The standard deviation of 43 marks, around 21.5 percentage points, is exceptionally wide, placing a candidate one deviation below the mean at 18.5%, deep into failing territory. This is a moderate-risk paper where the average candidate passes but the very large spread drops a substantial share well below the line. In a technical subject with this much volatility, accuracy across the whole paper is what keeps a candidate safely above the threshold. Statistically the small gap between a 42% median and a 40% mean reflects a mild left skew, where the weakest scripts pull the average down a touch, so the middle candidate scores just above the headline mean.
Provincial Breakdown
Punjab took 3 of the 4 seats, with Sindh Urban taking the fourth. With only four allocations there is little distribution to interpret beyond the usual concentration in Punjab.
Physics suits candidates with a strong scientific foundation who can deliver accurate, complete solutions under exam pressure, and even they should note how few succeeded in 2025. Four allocations from 292 applicants is a slim record. The very wide scoring spread rewards genuine technical command and punishes partial preparation severely.
Physics candidates averaged 40.0% of the available marks, in line with fellow Group-2 subjects Chemistry (40.5%) and Statistics (46.0%).

Frequently Asked Questions
What was the pass rate for Physics in CSS 2025?+
In CSS 2025, 292 candidates appeared for Physics and 6 cleared the written exam — a written pass rate of 2.05%. Of those who passed, 4 went on to be allocated a group, an overall selection rate of 1.37% of everyone who appeared.
How well do candidates typically score in Physics for CSS?+
Physics candidates scored a median of 42.3% of the paper's marks in CSS 2025 (median 84.5 out of 200; mean 40.0%), rating it "Average Scoring". Marking was also highly variable in 2025, so individual outcomes are less predictable.
How competitive is Physics for CSS allocation?+
6 candidates cleared the written stage for Physics in 2025, and 67% of them were allocated a group — a "Low Competition" level for the available seats. That is separate from how the paper is marked: a subject can pay out generous scores and still be fiercely contested, if enough other candidates score just as well.
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.
