BPSC AEDO Syllabus 2026: Paper-wise Topics and Preparation Guide
The BPSC AEDO syllabus covers three objective papers set by the Bihar Public Service Commission for the Assistant Education Development Officer recruitment under Advertisement No. 87/2025: General Language, General Studies and General Aptitude. With the April 2026 exam cancelled and a re-exam awaited, the syllabus remains the same, so the time you spend on it now carries straight into the next sitting.
The official notification gives each paper as broad headings rather than a chapter list. This guide turns those headings into a working checklist, shows which paper actually decides your rank, and suggests where to start in each subject. Use it alongside the notification, not in place of it.
Table of Contents
BPSC AEDO Syllabus at a Glance
Paper | Sections | Questions | Marks | Time | Role in selection |
|---|---|---|---|---|---|
Paper 1: General Language | Part 1 English (30 marks), Part 2 Hindi (70 marks) | 100 | 100 | 2 hours | Qualifying only |
Paper 2: General Studies | Science, current events, history, geography, polity, economy, national movement | 100 | 100 | 2 hours | Counted in merit |
Paper 3: General Aptitude | Mathematical ability, reasoning and mental ability | 100 | 100 | 2 hours | Counted in merit |
Total | - | 300 | 300 | 6 hours | Merit out of 200 |
All three papers are objective and conducted offline on OMR sheets. One-third of a mark is deducted for each wrong answer.
Key Points to Know Before You Start
Two papers decide your rank: General Studies and General Aptitude are the only papers counted in the merit list. Together they are worth 200 marks.
Paper 1 is a gate, not a scorer: As widely reported from the notification, you need at least 30% in the English part and at least 30% in the Hindi part. Missing either one ends your candidature, whatever your other scores.
Bihar carries real weight in GS: The General Studies syllabus names Bihar's history, geography, rivers, economy and role in the freedom struggle. State-specific preparation is essential, not optional.
The syllabus has not changed for the re-exam: The re-exam is a fresh sitting of the same recruitment. Unless BPSC issues a corrigendum, prepare for the notified scheme.
Ignore stray topic additions: Some pages add "education and development" or "rural development" chapters to this syllabus. The notification does not list them, so do not divert time to them.
Paper 1: General Language Syllabus
Paper 1 tests basic command of English and Hindi. The notification describes it in general terms: comprehension, grammar and appropriate usage of the language. The topic lists below are built from that description and from the areas these papers normally test. Use them as a working checklist rather than an official list.
Part 1: General English (30 Marks)
Area | Topics to cover | Start with |
|---|---|---|
Comprehension | Unseen passages, central idea, inference, vocabulary in context | One short passage a day |
Grammar | Tenses, subject-verb agreement, articles, prepositions, voice, narration, error spotting, sentence improvement | Error spotting and prepositions |
Usage | Sentence completion, fill in the blanks, sentence arrangement, idioms and phrases | Fill in the blanks |
Vocabulary | Synonyms, antonyms, one-word substitution, spelling | Common synonym and antonym lists |
At 30 marks, the 30% threshold means only 9 marks in English, but the negative marking makes careless guessing risky. Aim for a comfortable 15 or more so a hard passage does not put you at risk.
Part 2: General Hindi (70 Marks)
Area | Topics to cover | Start with |
|---|---|---|
Vyakaran (grammar) | Sandhi, samas, upsarg, pratyay, sangya, sarvanam, visheshan, kriya, ling, vachan, karak | Sandhi and samas |
Shabd gyan (vocabulary) | Paryayvachi, vilom, anekarthi shabd, ek shabd, tatsam and tadbhav | Paryayvachi and vilom |
Vakya rachna (sentences) | Vakya shuddhi, vartani (spelling) correction, vakya ke bhed | Vartani and vakya shuddhi |
Bhasha prayog (usage) | Muhavare, lokoktiyan, apathit gadyansh (unseen passage) | Muhavare with meanings |
Hindi carries 70 of the 100 marks in Paper 1, so it needs regular attention even for candidates who write Hindi daily. Grammar terms like sandhi viched and samas vigrah are rule-based, and short daily practice is the fastest way to make them automatic.
Paper 2: General Studies Syllabus
General Studies is one of the two merit papers. The notification groups it into a few broad areas, with an explicit focus on Bihar. The table maps each area to the topics you should actually study.
Area | Topics to cover | Start with |
|---|---|---|
General Science | Everyday physics, chemistry and biology; human body and health; basic scientific developments | Biology and everyday physics |
Current events | National and international events of social importance, government schemes, awards, sports, appointments | The last 12 months of national and Bihar news |
History of India | Ancient, medieval and modern India; major dynasties, rulers and reforms | Modern India |
History of Bihar | Magadh and its empires, Buddhism and Jainism in Bihar, medieval Bihar, Bihar in the colonial era | Ancient Bihar (Magadh, Maurya, Gupta) |
Geography | General geography of India and the world; physical divisions of Bihar; major rivers of Bihar | Bihar's rivers and physical divisions |
Indian Polity | Constitution, Parliament, executive, judiciary, state government, panchayati raj | Fundamental rights, duties and Parliament |
Economy | Indian economy basics, planning, budget terms; Bihar's economy and its major changes after independence | Bihar economy and state schemes |
Indian National Movement | Freedom struggle phases, key leaders and movements; Bihar's role, including Champaran and the Quit India movement | Champaran Satyagraha and Bihar leaders |
Bihar-Specific Topics to Prioritise
Rivers and physical divisions: Ganga, Kosi, Gandak, Son, Bagmati and Punpun, plus the north and south Bihar plains. Questions often ask about origin, tributaries and flood-prone areas.
Ancient heritage: Nalanda, Vikramshila, Vaishali, Rajgir, Pataliputra and Bodh Gaya, with the dynasties linked to each.
Freedom struggle in Bihar: Champaran Satyagraha, Rajendra Prasad, Jayaprakash Narayan, Babu Kunwar Singh and the 1857 revolt in Bihar.
Economy and schemes: The latest Bihar Economic Survey highlights, agriculture and major state welfare schemes in education and social sectors.
Given the post, keep an eye on current education-related schemes and policies too. They sit naturally under current events and government schemes, which the syllabus does cover.
Paper 3: General Aptitude Syllabus
General Aptitude is the second merit paper and the one where steady practice turns into marks most reliably. It has two parts: mathematical ability and reasoning or mental ability.
Mathematical Ability
Area | Topics to cover | Start with |
|---|---|---|
Number basics | Number system, whole numbers, decimals and fractions, relationships between numbers, basic arithmetic operations, simplification | Simplification and fractions |
Core arithmetic | Percentage, ratio and proportion, average, simple and compound interest, profit and loss | Percentage (it feeds most other chapters) |
Applied arithmetic | Time and work, pipes and cisterns, time and distance | Time and work |
Data interpretation | Tables, bar graphs, line graphs and pie charts | Table and bar graph sets |
Some summaries also list elementary algebra, geometry and statistics. These do not appear as named headings in the official scheme, so treat them as light practice areas after the core arithmetic is secure.
Reasoning and Mental Ability
Type | Topics to cover |
|---|---|
Verbal reasoning | Analogy, similarities and differences, classification, coding and decoding, relationship concepts, arithmetical reasoning |
Series | Arithmetical number series, letter series, non-verbal (figure) series |
Non-verbal reasoning | Space visualisation, spatial orientation, figure classification, visual memory |
Analytical ability | Problem solving, analysis, judgement, decision making, discrimination and observation |
Coding-decoding, series and analogy are fast scorers once you know the common patterns. Spatial and figure questions need visual practice, so solve them on paper rather than only reading solutions.
Where the Papers Overlap
Area | Paper 1 | Paper 2 | Paper 3 | How to plan |
|---|---|---|---|---|
Reading comprehension | English and Hindi passages | Reading long statements | Reading DI and word problems | Daily passage reading improves all three |
Numbers and data | - | Economy figures, budget terms | Arithmetic and DI | Learn percentage and ratio once, use everywhere |
Bihar knowledge | Passages may be on Bihar topics | History, geography, economy | - | One Bihar GK notebook for the whole exam |
Logical thinking | Sentence arrangement | Statement-based questions | Reasoning | Elimination skills transfer across papers |
How to Prioritise the Syllabus
Every topic is not equal. A simple rule: spend most of your time where marks count, and enough time on Paper 1 to clear it with a safe margin.
Priority | What to study | Suggested share of study time |
|---|---|---|
High | General Aptitude (arithmetic and reasoning) and Bihar GK | About 40% |
High | Rest of General Studies, especially current events, polity and history | About 35% |
Steady | General Hindi grammar and vocabulary | About 15% |
Steady | General English grammar and comprehension | About 10% |
These shares are a starting point, not a rule. If your mock scores show Hindi below the safe mark, move time towards it until it is stable.
Common Syllabus Mistakes to Avoid
Treating Paper 1 as a formality: Many strong GS candidates assume the language paper is easy and skip Hindi practice. With 70 marks of Hindi and negative marking, an unprepared attempt can fall below the qualifying mark.
Reading national GK only: Generic GK books cover India well but give Bihar a few pages. Keep a separate Bihar source for history, geography, economy and state schemes.
Collecting too many sources: One standard book per subject plus monthly current affairs notes is enough. Revising one source three times beats reading three sources once.
Learning DI and reasoning by reading: Aptitude improves only through timed solving. Watching solutions without attempting questions gives a false sense of readiness.
Leaving current affairs to the end: With the re-exam date unknown, current events from the past year keep building up. A short daily routine is far easier than a last-minute catch-up.
A Phased Plan to Cover the Syllabus
The re-exam date is not yet announced, so build a plan you can compress if the notice comes early.
Weeks 1 to 6, foundations: Cover number basics, percentage, ratio and the main reasoning types. In GS, finish Bihar history and geography from one standard source. Give Hindi grammar 20 minutes and English 15 minutes daily.
Weeks 7 to 12, full coverage: Complete applied arithmetic and data interpretation. Add Indian polity, economy, general science and the national movement. Start 30 to 40 minutes of current affairs a day with monthly notes.
Weeks 13 onwards, testing: Take topic tests and sectional tests, then full papers in the real order. Analyse each test the same day and keep an error log by topic.
Final four weeks: Revise from your notes and error log only, solve previous papers, and take full-length mocks back to back to build stamina for six hours of OMR work.
The cancelled April 2026 question papers are a useful guide to difficulty and topic spread, since they were set on this exact syllabus. BPSC does not publish an official online mock test for this exam, so keep the official BPSC website as your source for notices and corrigenda.
