BBISE Matric (SSC) Computer Science (Class IX): syllabus, papers and marking
The 60-mark Class IX theory paper, plus an 8-mark practical-based assessment, from BBISE’s September 2026 model paper.
BBISE Computer Science model paper and PBA syllabus for Class IX, published 9 September 2026 · Annual and Second Annual series · grades A++ to U (IBCC scale)
BBISE Matric Computer Science: where the marks go
BBISE’s Class IX Computer model paper sets 60 theory marks in 2 hours 40 minutes: 12 MCQs, ten of fifteen three-mark questions and three six-mark questions with an either-or alternative, followed by an 8-mark practical-based assessment. A project-based assessment of 7 marks makes up the other half of the practical marks.
The questions cover systems and troubleshooting, networks, data science, HTML and JavaScript, computational thinking and software. Marks go on exact definitions and clear explanations. Our papers follow the published structure.
Paper structure and what we mark
| Paper | Time | Marks | Weight | Questions |
|---|---|---|---|---|
| Class IX · Part A — Multiple Choice (Class IX) | 2 h 40 min (whole paper) | 12 | 17.6% | 12 MCQs, 1 mark each (the model paper prints 14) |
| Class IX · Part B — Short Answers (Class IX) | — | 30 | 44.1% | Any 10 short questions, 3 marks each |
| Class IX · Part C — 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 questions (2 × 3 marks) plus 2 marks on a favourite practical with its program |
Syllabus outline
- Topics tested in the September 2026 model paper (the board has not posted a unit list):
- Systems and the troubleshooting process
- Software, operating systems and utilities
- Networks, DNS, LAN and WAN
- Data and data science workflow
- HTML and JavaScript
- Computational thinking and algorithms
- Social networking and digital entrepreneurship
How each paper is marked here
- The twelve MCQs are scored automatically against the key.
- Short answers are marked on the definition and an example; six-mark answers on the discussion and its balance.
- The practical and project assessments are separate.
Where BBISE Matric Computer Science candidates lose marks
- Number-system conversions left half done — Binary, octal and hexadecimal conversions are marked on the working column; stopping at the remainders without reading them in order loses the answer.
- Truth table or logic diagram with one row wrong — A single wrong row or an unlabelled gate costs the whole question’s accuracy mark.
- Code that is correct in idea but not in syntax — Missing semicolons, wrong operators or an unclosed block in a program or HTML question are credited only partially.
- Definitions with no example — Short questions on networks, systems and software expect a definition and one concrete example.

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.
- Why does the model paper show 14 MCQs?
- The paper heading says 12 × 1 = 12 but prints 14 questions; we follow the printed heading.
- 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 Computer Science. 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 computer science model paper and pba syllabus for class ix, published 9 september 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 A 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).
