GSA stands out among compulsory subjects because it rewards clarity of concept, basic arithmetic practice, and structured reasoning. However, with such a diverse syllabus—ranging from physics to computer science and algebra to coding—it’s impossible to prepare everything with equal depth. This is where expected topics play a crucial role.

Why You Should Focus on Most Expected Topics
Every CSS topper knows one secret: covering what matters most. The most expected topics in GSA are drawn from repeated paper trends, current scientific relevance, and concepts that appear frequently across competitive exams. Expected topics reflect examiner patterns and focus areas, help you manage time effectively, and allow you to prepare smarter, not just harder.
Most Expected Topics of the General Science Portion
The General Science section is broad, but some topics have repeatedly appeared and continue to be highly likely in future papers. These topics should form the foundation of your preparation.
1. Physical Sciences
Expect frequent questions from
- Astronomy: Solar system, black holes, eclipses, earth's motion, and space-related phenomena.
- Energy: Renewable vs. non-renewable energy, solar panels, electricity generation.
- Modern Physics: Radioactivity, isotopes, nuclear fusion/fission, types of radiation.
- Natural Disasters: Earthquakes, tsunamis, floods, and cyclone mechanisms.
- Material Science: Semiconductors, polymers, fertilizers, ceramics.
2. Biological Sciences & Health
This section emphasizes human systems and real-world biological issues including
- Cell Biology: Cell structure, nucleus, mitochondria, DNA/RNA functions.
- Biomolecules: Functions of proteins, carbohydrates, and vitamins.
- Human Physiology: Digestive, respiratory, circulatory, and excretory systems.
- Diseases: Dengue, polio, hepatitis, tuberculosis, and their vaccines.
- Microorganisms: Roles of bacteria and viruses in health and environment.
3. Environmental Science
Given climate-related global events, you can almost always expect questions from
- Pollution: Air, water, and land—causes, effects, solutions.
- Climate Change: Global warming, greenhouse gases, carbon footprint.
- Conservation: Sustainable development, deforestation, and water conservation.
4. Food and Nutrition
Often neglected but frequently asked:
- Balanced Diet: Food groups and functions.
- Food Preservation & Adulteration: Types, detection, and impact.
- Deficiency Diseases: Symptoms of lack of vitamins, minerals, or proteins.
5. Information Technology
With Pakistan's increasing digital shift, expect IT-related questions, especially in objective sections. Focus on:
- Basics of Computer Systems: Input/output devices, software vs. hardware.
- Memory Types: RAM, ROM, cache, hard disks, memory units (bit to terabyte).
- Internet Literacy: Web browsers, search engines.
- Modern Means of Communication: Fiber Optics,
Most Expected Topics of the General Ability Portion
The Ability portion tests your command over numbers, logic, and analysis. Based on trends, these are the most expected categories:
1. Arithmetic and Word Problems
- Ratios, percentages, profit/loss, and discounts are ever-present.
- Time and work as well as age-based problems often reappear in MCQs.
- Probability is gaining popularity in recent years.
2. Algebra and Geometry
- Simple equations, averages, and number patterns (odd/even, sequence rules).
- Areas, perimeters, and geometry of basic shapes are expected in diagrams or calculations.
3. Statistics and Graphs
- Basic understanding of mean, median, mode, and range is essential.
- Pie charts, bar graphs, and line graphs often appear in interpretation-based questions.
4. Logical Reasoning
- Coding-decoding, series, direction sense, and blood relations are typical pattern-based questions.
How to Get Free Access to Solved Past Papers
One of the smartest moves you can make is to study from CSS solved GSA past papers, especially those curated by CSS mentors like Miss Iqra Ali and Sir Ammar Hashmi. These educators have not only compiled repeated questions from 2011–2025 but also provided easy explanations, diagrams, formulas, and clear strategies for answering.
