Punjab Boards Matric (SSC) Chemistry (Classes IX and X): syllabus, papers and marking
Same 12 + 48 layout as Physics, with equations and mole calculations marked step by step and short answers checked for the defining idea.
PECTAA Smart Syllabus and pairing scheme for Annual 2026 (Class IX, new textbook); Class X from the latest published Punjab model paper · First Annual and Second Annual series · grades A++ to U (IBCC scale)
Punjab Matric Chemistry: where the marks go
Punjab Matric Chemistry is a 60-mark theory paper in each of Class IX and Class X, with a separate 30-mark practical in Class X. The Class IX paper now follows the new textbook of eleven chapters, from States of Matter and Phase Change to Hydrocarbons. The 2026 pairing scheme fixes the MCQ count and the number of short questions per chapter, and puts one detailed question on each pair of chapters.
Marks are lost on unbalanced equations, mole calculations that start from a wrong molar mass, and definitions that name an example instead of the property. Our papers follow the pairing scheme exactly, and marked scripts show where the working broke down.
Paper structure and what we mark

| Class IX · Subjective — Short and Detailed Answers (Class IX) | 1 h 45 min | 48 | 32% | Q2–Q4: any 5 of 8 short answers each, 2 marks (30). Q5–Q7: any 2 of 3 detailed questions, 9 marks each, part (a) 5 and part (b) 4 (18) |
| Class X · MCQs — Multiple Choice (Class X) | 15 min | 12 | 8% | 12 MCQs on a bubble sheet, 1 mark each |
| Class X · Subjective — Short and Detailed Answers (Class X) | 1 h 45 min | 48 | 32% | Q2–Q4: any 5 of 8 short answers each, 2 marks (30). Q5–Q7: any 2 of 3 detailed questions, 9 marks each (18) |
| Class X · Practical — Practical (Class X) | — | 30 | 20% | Practical examination sat at the centre, marks added to the theory total |

How each paper is marked here
- The twelve MCQs are scored automatically against the key.
- Short answers are marked on the key idea the board expects, and detailed questions on part (a) and part (b) separately.
- Equations are credited for correct formulae first and balancing second, so partial credit is visible line by line.
Where Punjab Matric Chemistry candidates lose marks
- Equation not balanced, or state symbols missing — A correct reaction with the wrong coefficients loses the mark; balance first, then add (s), (l), (g) or (aq) where the question asks for them.
- Mole calculation with the wrong molar mass — Stoichiometry answers fail at the first step when the molar mass is added up wrongly; the rest of the working then cannot earn its marks.
- Definition that names the example, not the idea — Terms such as electronegativity, ionisation energy, equilibrium constant or isotope need the property itself; an example alone is not enough.
- Organic reactions with the wrong conditions — Naming the product but leaving out the reagent, catalyst or temperature (for example for dehydration or hydrogenation) is a standard half-mark loss.
- Trends stated without the reason — Periodic-table questions ask for the trend and the reason (shielding, nuclear charge, size); the trend alone earns half.

Questions teachers ask
- Why do the Class IX and Class X papers look different?
- Class IX is on the new textbook and the 2026 pairing scheme. Class X still uses the structure of the last published Class X model paper until the board issues a new one.
- Are practical skills tested?
- The 30-mark Class X practical is separate and sat at the centre. We build theory papers only.
- Is this official Punjab Boards marking?
- No. Boards of Intermediate and Secondary Education, Punjab marks the real exam. This is examiner-style marking of mocks and homework for Punjab Matric Chemistry. Only you see the marking, and you decide what reaches the student.
- Do you reproduce past-paper questions?
- No. Every Classes IX and X paper here is original and written to the pectaa smart syllabus and pairing scheme for annual 2026 (class ix, new textbook); class x from the latest published punjab model paper, in the same structure as the real papers shown above.
- Which papers are marked?
- None yet are marked question by question; Class IX · MCQs, Class X · MCQs are scored instantly. Practical exams sat at the centre are not marked here.
- How is the next paper chosen?
- From the marks a student lost: the concepts behind them are ranked by marks dropped, and the new paper weights those topics. It is the same syllabus and structure, with new questions.
- When are the exams?
- First Annual and Second Annual series. Grades A++ to U (IBCC scale).
