BBISE Inter Physics: where the marks go
BBISE’s HSSC-I Physics model paper (October 2026) is 80 theory marks plus a 10-mark practical-based assessment, 90 in all: 17 MCQs, any 13 of the short questions at 3 marks (39), and four six-mark questions, each with two alternatives of which one is answered (24), in a 3-hour paper.
The model questions ask for the time of flight and maximum height of a projectile, Bernoulli’s principle, entropy and the second law, Young’s modulus and time dilation with length contraction. Marks go on correct derivations and unit-careful numericals.
Paper structure and what we mark
| Paper | Time | Marks | Weight | Questions |
|---|---|---|---|---|
| Class XI · Section 1 — Multiple Choice (Class XI) | 3 h (whole paper) | 17 | 18.9% | 17 MCQs, 1 mark each: write the question number and the correct option on the answer script |
| Class XI · Section 2 — Short Answers (Class XI) | — | 39 | 43.3% | Any 13 questions, 3 marks each |
| Class XI · Section 3 — Detailed Answers (Class XI) | — | 24 | 26.7% | Four questions of 6 marks, each with two alternatives (answer one) |
| Class XI · Section 4 — Practical Based Assessment (Class XI) | — | 10 | 11.1% | Any 2 of 3 PBA questions, 2 × 4 marks, plus 2 marks (8 + 2) |
Syllabus outline
- Topics tested in the October 2026 model paper (the board has not posted a unit list):
- Vectors and projectile motion
- Kinematics and graphs
- Fluid flow and Bernoulli’s principle
- Simple harmonic motion
- Thermodynamics and entropy
- Elasticity and Young’s modulus
- Special relativity: time dilation and length contraction
How each paper is marked here
- The seventeen MCQs are scored automatically against the key.
- Short answers are marked on the key point; six-mark answers on each stated step.
- The practical-based assessment is separate and not part of our theory marking.
Where BBISE Inter Physics candidates lose marks
- Unit missing or wrong in the final answer — A numerical answer such as 12 instead of 12 m s⁻² usually loses the last mark even when the working is right. Prefixes (milli, micro, femto, kilo) are tested directly.
- A definition without its defining condition — Short answers such as uniform acceleration, moment of a force or Pascal’s law need the quantity, the condition and the unit. The loose everyday version scores half.
- A derivation that skips an assumption — In derivations (second law, kinetic energy, simple pendulum, hydraulic press) marks are split by step, and an unstated starting condition costs a mark even when the algebra is correct.
- Graphs described in words, not drawn — Gradient and area questions on distance-time and velocity-time graphs expect a labelled sketch with axes, not a paragraph.
- Free-body diagram with a force missing — Dynamics and equilibrium answers lose everything after the diagram if weight, normal reaction, tension or friction is left out or drawn in the wrong direction.

Questions teachers ask
- Why is there only Class XI?
- BBISE’s October 2026 model papers are published for HSSC-I (Class XI) only; a Class XII layout has not been verified.
- What is the 8 + 2 practical mark?
- Section 4 is a practical-based assessment: two of three questions (8 marks) plus 2 marks, so the paper is 90 marks with 80 theory.
- 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 Inter Physics. Only you see the marking, and you decide what reaches the student.
- Do you reproduce past-paper questions?
- No. Every Class XI paper here is original and written to the bbise hssc-i model papers, published 11 october 2026, in the same structure as the real papers shown above.
- Which papers are marked?
- None yet are marked question by question; Class XI · Section 1 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).
