Punjab Inter Biology: where the marks go
Intermediate Biology in Punjab is 200 marks: Part I 85, Part II 85 and a 30-mark practical. Part I uses the new twelve-chapter book (Biodiversity and Classification through Human Skeletal and Muscular Systems), and the 2026 Smart Syllabus deletes chapter 8, Plant Physiology, entirely. The pairing scheme sets the MCQs per chapter and pairs chapters in the five detailed questions, each with two four-mark parts.
Marks go on exact terminology, labelled diagrams and complete pathways. Our papers follow the chapter allocation and mark each part of a detailed question separately.

- Detailed questions are marked as two four-mark parts, with diagram and labels credited separately.
- Short answers are marked on keywords and the reason asked for.
Where Punjab Inter Biology candidates lose marks
- Diagrams without labels — Detailed answers on systems and organs earn marks for the labels.
- Short answers that define but do not explain — Many two-mark questions ask why or how; the cause is the mark.
- Pathways with the wrong enzyme or order — Respiration, circulation and excretion pathways are marked step by step.
- Disorders described without cause and treatment — Disorder questions (arthritis, thyroid, kidney stones) expect cause and a control or treatment.

Questions teachers ask
- Which chapters are removed in 2026?
- The Smart Syllabus deletes Plant Physiology (chapter 8) in full and trims sections from most other chapters.
- Is Part II on the new book?
- The new pairing scheme is published for Part I. For Part II we use the latest published model-paper structure (17 MCQs, 16 + 16 + 12 short marks and three detailed questions of eight marks).
- 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 Biology. 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).
