BPSC AEDO Syllabus, Exam Pattern, Eligibility

One written exam, three papers, all objective. Each question carries one mark and a wrong answer costs one third of a mark.

In the language paper you need at least 30% in English and 30% in Hindi separately. Miss either and your other two papers are not marked. Language marks do not count towards the merit list.

Because the exam runs in several phases, the Commission said in its December 2025 corrigendum that scores would be normalised with equipercentile equating before the result.

BPSC also changed its answer sheets from May 2026: every question now has a fifth option, E, for "not attempted". Leaving a question with no bubble filled at all costs one third of a mark, the same as a wrong answer. Expect this in the re-exam.

• General Language: questions in English and Hindi that test how well you understand and use each language.
• General Studies: general science, current events of national and international importance, Indian history and the main features of Bihar's history, general geography and the main geographical regions of Bihar, its important rivers, Indian polity and economy, major changes in Bihar's economy since independence, the national movement and Bihar's part in it.
• General Aptitude: number system, whole numbers, decimals and fractions, basic arithmetic operations, percentage, ratio and proportion, average, interest, profit and loss, analogy, similarities and differences, spatial visualisation and orientation, problem solving, analysis, visual memory, discrimination, observation, relationship concepts, arithmetical reasoning, verbal and figure classification, number series, non-verbal series, coding and decoding.

• Qualification: a graduate degree, or equivalent, from a recognised university. Any subject.
• Age on 1 August 2025: at least 21. Upper limit 37 for unreserved men, 40 for unreserved women and for BC and EBC candidates, 42 for SC and ST candidates.
• Relaxation: 10 more years for candidates with a benchmark disability. Ex-servicemen get 3 years plus their service, as long as they are not over 57. Bihar government employees get 5 years, but only while they have attempts left out of the five BPSC exams allowed to them across their service.
• Reservation is only for original residents of Bihar. Candidates from other states can apply but are treated as unreserved.

1. Written exam (no interview).
2. Document verification for those who clear the cut-off. Bring originals of every certificate you claimed in the online form.
3. Final merit list on written marks.

Minimum marks to be considered: 40% for unreserved, 36.5% for BC, 34% for EBC, and 32% for SC, ST, women and candidates with disability. On a tie, the higher General Studies score ranks first, then the older candidate, then Devanagari alphabetical order of name. There is no re-evaluation of answer sheets.

Pay Level 5, starting basic pay ₹29,200 a month, plus the allowances the Bihar government pays at that level.

Apply online only, on bpsconline.bihar.gov.in. Do not post a hard copy. The fee is ₹100 for every candidate. If you do not give an Aadhaar number as your ID, you pay a further ₹200 as a biometric fee.

The reopening in December did not move the eligibility date: qualifications and certificates still had to be held by 26 September 2025.

No cut-off has been published because the April 2026 exam was cancelled before any result. The minimum qualifying percentages under Selection Process are the floor, not the cut-off.

• Hindi is 70 of the 100 language marks. If your Hindi grammar is weak, work on it early: failing this paper means your other two papers are never marked.
• General Studies leans on Bihar: its history, rivers, economy and the freedom movement. Prepare those topics in more depth than a national GK book gives.
• General Aptitude is mostly class 10 arithmetic plus reasoning. Timed practice matters more than new theory, as there are 100 questions in two hours.
• With option E and a one-third penalty, mark E for anything you are guessing blindly.
