WBCS Syllabus 2026: Prelims, Mains and Optional Subjects
The WBCS syllabus is set by the West Bengal Public Service Commission (WBPSC) for the West Bengal Civil Service (Executive) etc. Examination. It covers an objective preliminary exam, a Main exam with language, General Studies and optional papers, and a personality test. The current recruitment, the WBCS (Exe.) etc. Examination, 2024 (Advt. No. 08/2024), follows the older scheme, while a revised scheme applies from the 2025 examination onward.
This page gives a subject-wise WBCS prelims syllabus, a paper-wise mains syllabus, the full optional subject list and a simple plan to cover it all. WBPSC's official syllabus lists headings for several papers rather than chapter-wise topics, so the topic lists below combine the official headings with areas asked in previous papers. Use them as a working checklist.

Mains becomes fully descriptive from 2025: The objective Mains papers are replaced by an essay, a Bengal culture paper and four General Studies papers.

Reasoning | Series, analogy, classification, coding-decoding, blood relations, direction sense, seating arrangement, syllogism, statement and conclusion, puzzles |
WBCS Optional Subjects List
Group A and B candidates choose one optional subject and write two papers in it. The list below is grouped for easier reading.
Category | Optional subjects |
|---|---|
Languages and literature | Bengali, Hindi, Sanskrit, English, Pali, Arabic, Persian, French, Urdu, Santali, Comparative Literature |
Humanities and social sciences | History, Political Science, Economics, Geography, Sociology, Anthropology, Philosophy, Psychology, Law |
Sciences and mathematics | Physics, Chemistry, Botany, Zoology, Geology, Physiology, Mathematics, Statistics, Computer Science |
Professional and technical | Agriculture, Animal Husbandry and Veterinary Science, Civil Engineering, Electrical Engineering, Mechanical Engineering, Medical Science, Commerce and Accountancy, Management |
Choose the optional on three tests: your comfort with the subject from graduation, the availability of good study material, and how much it overlaps with General Studies. History, Geography and Political Science overlap most with the compulsory papers, but a subject you know well usually scores better than a popular one you are starting from scratch.
WBCS New Syllabus from 2025
WBPSC has notified a revised scheme and syllabus that applies from the WBCS (Exe.) etc. Examination, 2025. Its broad structure is summarised below. The detailed advertisement for the 2025 cycle will carry the final paper-wise syllabus, so check it before you plan around these figures.
Stage | Paper | Nature |
|---|---|---|
Prelims | General Studies Paper I | Objective, screening |
Prelims | General Studies Paper II (comprehension, reasoning, decision making, numeracy, data interpretation) | Objective, qualifying (33% minimum) |
Mains | Bengali or Nepali language paper and English language paper | Descriptive, qualifying |
Mains | Essay | Descriptive, merit |
Mains | Tradition and Culture of Bengal | Descriptive, merit |
Mains | General Studies I to IV | Descriptive, merit |
Mains | Optional Papers I and II (Group A and B) | Descriptive, merit |
What this means for you:
Answer writing becomes central: With no objective Mains papers, regular answer-writing practice is essential from the start.
Bengal culture is a full paper: Art, architecture, music, literature and festivals of Bengal now need dedicated preparation, not just a few facts.
The aptitude paper is qualifying but risky: Candidates who ignore comprehension and numeracy can fail Paper II even with a strong GS score.
West Bengal Topics to Prepare
State-specific questions appear in prelims geography, history, current events and several Mains papers. Keeping one consolidated West Bengal notebook avoids scattered revision.
Area | What to cover |
|---|---|
Geography | Districts and divisions, physiographic regions, rivers such as the Ganga, Hooghly, Damodar and Teesta, the Sundarbans, climate, soils, major crops and mineral areas |
History and freedom struggle | Bengal Renaissance and reformers, partition of Bengal in 1905, revolutionary groups, Bengal's leaders in the national movement |
Economy and governance | Major state schemes, industries, agriculture, Panchayati Raj in West Bengal, state budget highlights |
Culture | Literature, folk music and dance, festivals and heritage sites; this becomes a full Mains paper from 2025 |
Overlap Between Prelims and Mains
Area | Prelims | Mains (2024 scheme) | How to plan |
|---|---|---|---|
History and National Movement | 50 marks across two subjects | Paper III | Study once in depth; it serves both stages |
Geography with West Bengal | 25 marks | Paper III | Use maps and keep a West Bengal fact sheet |
Polity and Economy | 25 marks | Paper V (full paper) | Go beyond basics; add the RBI and banking |
Science and Current Events | 50 marks across two subjects | Paper IV | Add environment and technology to daily notes |
General Mental Ability | 25 marks | Paper VI (with arithmetic) | Practise arithmetic from the start, not after prelims |
English | 25 marks (objective) | Paper II (descriptive) | Add weekly writing practice to grammar work |
Most of the prelims syllabus feeds directly into the objective Mains papers. That is why an integrated plan, rather than a prelims-only phase followed by a Mains-only phase, saves time.
Personality Test
There is no written syllabus for the interview. The board assesses your awareness of West Bengal and national affairs, your understanding of administration, your graduation subject, the details in your application form and your clarity of thought. Reading a daily newspaper with an administrative lens and preparing to explain your service preferences are the most useful steps.
How to Cover the WBCS Syllabus
Weeks 1 to 8, foundation: Build basics in history, geography, polity and economy from school-level books. Start a daily 30 to 40 minute current affairs habit and a short daily English and reasoning set.
Weeks 6 to 12, depth and West Bengal: Move to standard books, prepare West Bengal notes for geography, history and the economy, and begin your optional subject if you are targeting Group A or B.
Weeks 10 to 16, topic tests: Take topic-wise and sectional tests for all eight prelims subjects. Start arithmetic practice for Paper VI and one weekly writing exercise for the language papers.
Final phase, full-length mocks: Attempt full-length timed papers, analyse each one the same day and revise from an error log of repeated mistakes.
Always confirm the syllabus for your cycle in the official scheme and syllabus document on the WBPSC website.
