Computer Science past papers by year

Each card links straight to that year's original question paper as set by FPSC, with Paper-I and Paper-II included together. Reviewing several years in sequence is the fastest way to notice which programming concepts, algorithms, and systems topics examiners return to most often.

What the Computer Science paper actually tests

Computer Science is one of the 200-mark Group-I subjects, so candidates sit two separate three-hour papers instead of one. Both papers follow the same selection rule: attempt four questions from Part-II by choosing two from each of two sections.

Paper-I: Programming and foundational concepts Worth 100 marks across MCQs and four subjective questions, two from each section. Based on past papers, Section-I covers software licensing, cybersecurity, C++ programming and debugging, object-oriented programming, and cloud security. Section-II covers algorithms and data structures: genetic algorithms, AVL trees, graph algorithms like Kruskal's minimum spanning tree, aspect-oriented programming, and compiler optimization.

Paper-II: Systems and applied computing Also worth 100 marks with the same two-from-each-section format. Section-A covers computer architecture (CISC versus RISC, superscalar processing), computer networks (IPv4/IPv6, routing protocols, error detection), and operating systems (process scheduling, memory management, file access). Section-B covers digital image processing, software engineering (requirement engineering, cloud strategy), and database systems (ER modelling, security, distributed design).

This is a genuinely broad paper. Paper-I rewards strong programming fundamentals and algorithmic thinking, while Paper-II rewards systems-level knowledge across networking, operating systems, and databases, so a narrow focus on just programming or just theory will leave real gaps on exam day.

Programming and OOP C++ debugging, object-oriented design, and real-world OOP applications

Algorithms and data structures AVL trees, graph algorithms, and compiler code optimization

Computer architecture CISC versus RISC design, superscalar processing, and bus functions

Networks and security IPv4/IPv6, routing protocols, error detection, and cybersecurity concepts

Operating systems Process scheduling, memory management, and file access methods

Databases and software engineering ER modelling, database security, requirement engineering, and cloud strategy

How to use these papers effectively

Because this subject spans so many CS domains, use past papers to map out which topics repeat most often within each section, rather than trying to master every possible computer science topic equally. Programming and algorithms tend to reward deep practice, while systems topics like networking and databases respond well to structured notes and diagrams.

Practise writing full answers under timed conditions, especially for programming questions like the C++ debugging task in past papers, since spotting logical errors quickly under exam pressure is a different skill from understanding the code when you have unlimited time to review it.

Frequently asked questions

Where can I get authentic CSS Computer Science past papers?

The papers on this page are sourced from FPSC's published question papers and cross-checked for accuracy. You can also confirm recent years yourself on the official FPSC Previous Question Papers section, though FPSC generally keeps only the last few years live on its own site.

Why does Computer Science have two papers instead of one?

Computer Science is a 200-mark optional subject in Group-I, alongside Accountancy & Auditing, Economics, Political Science, and International Relations. Candidates choosing a 200-mark subject sit two separate three-hour papers, Paper-I and Paper-II, each worth 100 marks.

Does CSS Computer Science require actual coding, or just theory?

Based on past papers, both are tested. Questions have asked candidates to identify logical errors in given C++ code and explain programming concepts directly, alongside theoretical questions on architecture, networks, databases, and software engineering.

What topics does Computer Science Paper-II cover?

Paper-II covers systems-level topics: computer architecture, computer networks, operating systems, digital image processing, software engineering, and database systems, split across two sections with two questions required from each.

Are these Computer Science papers solved or unsolved?

These are original, unsolved question papers exactly as set by FPSC for both Paper-I and Paper-II.

Source and verification

Papers on this page are compiled from FPSC's official published question papers. Where a specific year was no longer available on FPSC's own site, it was cross-checked against independent archives before being added here, so you can rely on these as accurate representations of the original exam.
