2nd Year (Class 12) Computer Science students under the Punjab boards now have the official 2025 pairing scheme for their board exams. It covers BISE Lahore, Rawalpindi, Faisalabad, Sargodha, Gujranwala, Sahiwal, Multan, Bahawalpur, and Dera Ghazi Khan, along with the Azad Kashmir board, and lays out how the 75-mark theory paper is divided across all 14 chapters.
Second-year Computer Science mixes theory, error-correction and program-output questions, so the type of question matters as much as the chapter. This scheme shows the MCQ split, exactly which chapters carry theory vs. error vs. output-type short questions, and the choice-based pattern for the five long questions — so you know what to practice, not just what to read.

Exam Pattern Breakdown
MCQs — 15 Marks
| Chapter | MCQs | Chapter | MCQs | Chapter | MCQs |
|---|---|---|---|---|---|
| 1 | 1 | 6 | 1 | 11 | 1 |
| 2 | 1 | 7 | 0 | 12 | 2 |
| 3 | 1 | 8 | 2 | 13 | 1 |
| 4 | 1 | 9 | 1 | 14 | 1 |
| 5 | 1 | 10 | 1 |
The 15 MCQs are distributed across all 14 chapters; Chapter 7 carries none this time.
Short Questions — 36 Marks (Attempt any 6 out of 9 in each)
| Q.2 – Chapter | Qs | Q.3 – Chapter | Qs | Q.4 – Chapter | Qs |
|---|---|---|---|---|---|
| 1 | 3 | 8 | 3 | 11 | 3 |
| 2 | 2 | 10 | 4 | 12 | 3 |
| 4 | 2 | 14 | 2 | 13 | 3 |
| 5 | 2 |
Qs = number of questions offered from that chapter. Students attempt any 6 of the 9 offered in each of Q.2, Q.3 and Q.4. Q.3 and Q.4 mix theory, error-correction and output-based questions — see Important Things to Know below.
Long Questions — 24 Marks (Attempt 1 from Q.5–Q.6, 2 from Q.7–Q.9)
| Q.5 | Q.6 | Q.7 | Q.8 | Q.9 |
|---|---|---|---|---|
| Ch 3 | Ch 6 or Ch 7 | Ch 9 (Theory) | Ch 11 (Program) | Ch 12 |
Q.5 and Q.6 offer a choice — attempt any 1. Q.7, Q.8 and Q.9 offer three options — attempt any 2. Q.8 is program-based; the others are theory-based unless noted.
Important Things to Know
- Short questions from Ch.8, 10, 11, 12, 13 and 14 mix theory, error-correction and output-based types: Ch.8 (3 theory), Ch.10 (2 theory + 1 error + 1 output), Ch.14 (2 theory), Ch.11 (2 theory + 1 error), Ch.12 (1 theory + 1 error + 1 output), Ch.13 (3 theory).
- Long questions work differently here: Q.5/Q.6 is a pick-one choice, and Q.7/Q.8/Q.9 is a pick-two choice — read the instructions carefully in the real exam.
- Q.8 is the program-writing long question (Chapter 11) — practice writing full programs, not just reading code.
- The 2025 paper follows the SLO-based pattern, so it differs a little from older papers; even so, roughly 90% of this scheme is expected to hold.
- This scheme is built around Punjab boards. Prepare all chapters fully rather than relying on the scheme alone.

Who Should Use This Pairing Scheme
2nd Year (Class 12) students appearing in the 2025 Computer Science exam under any Punjab board or the Azad Kashmir board — regular college students and private candidates both.
Applicable Boards
Issued for all Punjab boards: Lahore, Rawalpindi, Faisalabad, Sargodha, Gujranwala, Sahiwal, Multan, Bahawalpur, and Dera Ghazi Khan. It also applies to the Azad Kashmir (AJK) board, which follows a similar paper pattern for Computer Science.
FAQs
Is this pairing scheme official for 2nd Year Computer Science 2025?
Yes, it reflects the pairing pattern issued for Punjab boards and AJK for the 2025 exams.
What do theory, error and output mean in the short questions table?
They describe the question type: theory questions test concepts, error questions ask you to fix code, and output questions ask what a given program prints.
Can students from other boards use it?
It is built for Punjab boards and AJK. Students from other boards should check their own board’s scheme.
Does the download include solved exercises?
No — this is the pairing (assessment) scheme only. It shows the marks distribution, not solved answers.
