BBISE Matric (SSC) Biology (Class IX): syllabus, papers and marking
The 60-mark Class IX theory paper of the new BBISE syllabus, in the 12 + 30 + 18 layout, plus an 8-mark practical-based assessment.
BBISE model papers for SSC-I Examination 2026 onwards (new syllabus), published 30 July 2026 · Annual and Second Annual series · grades A++ to U (IBCC scale)
BBISE Matric Biology: where the marks go
The BBISE Class IX Biology model paper sets 60 theory marks in 2 hours 40 minutes: 12 MCQs, ten of the three-mark questions and three six-mark questions with an either-or alternative. The practical-based assessment is worth 8 marks and asks, for example, about the nucleotide structure.
The paper rewards labelled diagrams and exact terminology. Our papers follow the published structure.
Paper structure and what we mark
| Paper | Time | Marks | Weight | Questions |
|---|---|---|---|---|
| Class IX · Part I — Multiple Choice (Class IX) | 2 h 40 min (whole paper) | 12 | 17.6% | 12 MCQs, 1 mark each; no cutting or erasing allowed |
| Class IX · Part II — Short Answers (Class IX) | — | 30 | 44.1% | Any 10 short questions, 3 marks each |
| Class IX · Part III — Detailed Answers (Class IX) | — | 18 | 26.5% | Three questions of 6 marks, each with an either-or alternative |
| Class IX · PBA — Practical Based Assessment (Class IX) | 20 min | 8 | 11.8% | Any 2 of 3 practical-based questions (2 × 3 marks) plus 2 marks on a favourite practical |
Syllabus outline
- Topics tested in the 2026 model paper (the board has not posted a chapter list):
- Cell and its organelles
- Nucleotide structure
- Biodiversity and classification
- Enzymes
- Nutrition and transport
How each paper is marked here
- The twelve MCQs are scored automatically against the key.
- Short answers are marked on keywords and the reason; detailed answers on the labelled diagram and each stated step.
- The practical-based assessment is separate.
Where BBISE Matric Biology candidates lose marks
- Diagram unlabelled or labelled with the wrong part — Detailed questions on the cell, nephron, heart or reproductive system award marks for the labels. An unlabelled sketch, however neat, scores little.
- Differences written as two separate descriptions — “Differentiate between” needs a point-by-point comparison on the same feature, in two columns or two parallel sentences.
- Process steps in the wrong order — Pathway questions (respiration, photosynthesis, urine formation, protein synthesis) are marked step by step; reversing two steps usually loses both.
- Reasoning questions answered with a definition — Where the paper asks “why” or “how does”, naming the structure and stopping scores zero; the cause or mechanism is the mark.
- Terminology approximated — Keywords such as osmosis versus diffusion, homologous versus analogous or genotype versus phenotype are credited only when used exactly.

Questions teachers ask
- Why is there only Class IX?
- BBISE’s 2026 model papers are published for Class IX (SSC-I) only; a Class X layout has not been verified.
- What does the practical-based assessment ask?
- The model paper’s PBA works from a labelled diagram, for example the components of a nucleotide, and is sat for 20 minutes for 8 marks.
- Is this official BBISE marking?
- No. Balochistan Board of Intermediate and Secondary Education, Quetta marks the real exam. This is examiner-style marking of mocks and homework for BBISE Matric Biology. Only you see the marking, and you decide what reaches the student.
- Do you reproduce past-paper questions?
- No. Every Class IX paper here is original and written to the bbise model papers for ssc-i examination 2026 onwards (new syllabus), published 30 july 2026, in the same structure as the real papers shown above.
- Which papers are marked?
- None yet are marked question by question; Class IX · Part I 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?
- Annual and Second Annual series. Grades A++ to U (IBCC scale).
