Two data scopes, kept separate
The live result card is fetched only after a submitted lookup. Cohort comparisons stay in the precomputed gazette artifacts, and the roll number is not stored permanently.
What counts as published
Anything the gazette prints in one of its own tables: headline totals, the salient-features tables (per area, group, gender and candidate type), subject statistics, position holders, and the HSSC-II institution table. These are copied, never recomputed — FBISE divides its grand-total row by appeared minus result-later, so recomputing it would disagree with the printed figure.
What counts as derived
Anything computed from the gazette’s candidate listing: mark distributions, medians and interquartile ranges, ranks and ties, grade proximity, mark clustering, per-institution mark spreads, and the per-candidate group and gender used on the HSSC tabs. Derived figures are labelled wherever they appear.
How the HSSC group split is derived
FBISE issues roll numbers in dense, widely separated blocks, one block per group and gender. The block a roll number sits in is matched against the published group table; the residual between the derived block totals and the published totals is stated on the Groups section itself. Nothing is inferred from a candidate’s name, subjects or institution.
Regular and ex/private candidates
The listing prints every regular candidate under their institution’s header and every ex/private candidate under an “Ex-Private Candidates” banner with no institution. Splitting on that reproduces both published totals exactly: 85,999 and 18,839 for HSSC-II, 99,326 and 7,182 for HSSC-I.
HSSC maximum marks and grade boundaries
Neither HSSC gazette prints a maximum or a grading scheme. The HSSC-II boundaries here are read back from the listing, where every row carries both a total and a grade: they fall at 440, 550, 660, 770 and 880 — equal steps of 110, which puts the certificate total at 1,100. HSSC-I publishes no grades and no maximum, so its cohort figures are shown on their own scale with no percentage.
HSSC paper maximums
Neither gazette prints a marks scheme, so the per-paper maximums used on a lookup result were read off the result cards themselves and anchored to the two totals the gazettes do fix: the 1,100 certificate the HSSC-II boundaries imply, and the Part-I combinations that reproduce it. They give 540 for Pre-Medical, 560 for Pre-Engineering and General/Computer Science, and 600 for Commerce and Pre-Home Economics. A percentage is shown only when every paper on that card resolves to a maximum, no paper scores above its own maximum, and the maximums add up to the total the gazette implies; otherwise the page shows raw marks. Hearing-impaired candidates sit several papers at other weights, and candidates who took a single subject for improvement have no certificate total at all — both fall through to raw marks rather than a percentage of a scheme that does not describe them. No pass mark is published for either HSSC exam, so no per-paper pass threshold is drawn.
HSSC practical marks
A practical is examined once for a subject and can be printed against one paper or against both. Its marks are pooled across that subject’s two papers and divided equally between them, so neither paper reads inflated beside its twin, and each row says how much was allocated to it. The candidate’s official total is never changed: across 130 sampled cards the redistributed papers still sum to exactly the total FBISE printed.
Additional-subject candidates
A small number of HSSC-II candidates sat an additional subject only. Their published total is that one subject’s mark, so they are counted in the headline totals exactly as the gazette counts them but excluded from every mark distribution, median and rank.
Where the map comes from, and where it does not
The HSSC-II gazette prints a full salient-features table for each of its eight areas, so the HSSC-2 map is drawn entirely from published figures and can be narrowed to one group or candidate type. The HSSC-I gazette prints a single ALL AREAS table and no area breakdown anywhere, so the HSSC-1 tab has no map: there is nothing published to draw.
SSC schemes
SSC-I totals are derived from the returned subjects: 555 for the published Science theory result and 600 for Humanities. On SSC-II science rows, the single composite practical score is divided equally between Part I and Part II for the two 75-mark comparisons; the official overall total is never changed.
