Punjab Inter Chemistry: where the marks go
Intermediate Chemistry in Punjab is 200 marks: 85 for each of Part I and Part II plus a 30-mark practical. Part I now follows the new sixteen-chapter book, from Periodic Table and Periodic Properties to Lab Safety and Practical Skills, though chapters 15 and 16 are deleted from the 2026 paper. The pairing scheme gives each chapter its MCQs, its short-question count and its place in one of five detailed questions.
Marks are won on balanced equations, accurate mole and equilibrium numericals and complete mechanisms. Our papers follow the chapter allocation and mark each part of a detailed question separately.

How each paper is marked here
- The seventeen MCQs in each paper are scored automatically against the key.
- Detailed questions are marked as two parts of four marks each, so one weak half does not sink the whole answer.
- Equations and mechanisms are credited step by step.
Where Punjab Inter Chemistry candidates lose marks
- Equilibrium and kinetics numericals with the wrong expression — A Kc or rate-law expression written wrongly sinks the whole numerical.
- Mechanisms drawn without arrows or charges — Organic mechanism marks go to curly arrows, intermediates and charges, not the product alone.
- Periodic trends with no reason — Variation in melting point or ionisation energy needs the structural reason.
- Units and significant figures in calculations — Mole, pH and electrochemistry answers lose a mark for a missing unit or wrong precision.

Questions teachers ask
- Which Part I chapters are not examined?
- The Smart Syllabus deletes chapters 15 and 16 in full, and trims sections from other chapters; paper-setters may not ask from deleted content.
- Is the practical marked?
- No. The 30-mark practical is separate from the theory papers we generate.
- 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 Inter Chemistry. Only you see the marking, and you decide what reaches the student.
- Do you reproduce past-paper questions?
- No. Every Parts I and II paper here is original and written to the pectaa smart syllabus and pairing scheme for annual 2026 (part i, new textbook); part ii 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; Part I · MCQs, Part II · 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).
