ITBP AC Engineer Previous Year Papers 2026 — Paper 1 & Paper 2 Analysis
ITBP Assistant Commandant Engineer is a Group A Gazetted post — the written exam is two papers, and both papers test very different things. Paper 1 is a standard 100-MCQ objective test. Paper 2 is a 100-mark subjective Civil Engineering paper that candidates consistently describe as IES-level difficulty. This article breaks down both papers using data from the 2019 exam cycle (the last confirmed written exam), the official 2026 notification, and the verified syllabus — so you know exactly what to prepare and how to prepare it.
Important: No official free-download PDFs of ITBP AC Engineer previous year papers exist on any public platform. The official ITBP website does not publish question papers. A YouTube video from March 12, 2019 (search: "ITBP AC Engineer EXAM Question Paper 1 & 2") shows the actual paper from the March 10, 2019 exam. That is the closest publicly accessible source for Paper 1 and Paper 2 content.
Exam History — When Has ITBP AC Engineer Exam Been Held
ITBP does not conduct this exam annually. The post is recruited in small batches with significant gaps between cycles:
| Notification Year | Vacancies | Written Exam Date | Status |
|---|---|---|---|
| 2018 (Aug notification) | 10 posts (Civil) | March 10, 2019 | Completed |
| 2022 (Jun notification) | Not confirmed | Not confirmed | Unknown |
| 2023 (Nov notification) | 6 posts (Civil) | Not yet held | In process |
| 2026 (Apr notification) | 6 posts (Civil) | TBA | Applications open |
The post is exclusively for Civil Engineers (B.E./B.Tech Civil Engineering). There is no Mechanical, Electrical, or Electronics variant under this specific ITBP Engineer post. The Telecom AC is a separate, unrelated recruitment.
Exam Pattern — Paper 1 (Objective) and Paper 2 (Subjective)
The selection process includes multiple qualifying stages (PST, PET, medical) before the written exam. The written exam carries actual marks:
| Stage | Marks | Nature |
|---|---|---|
| Physical Standard Test (PST) | — | Qualifying only |
| Physical Efficiency Test (PET) | — | Qualifying only |
| Written Exam — Paper 1 | 100 | Merit-based |
| Written Exam — Paper 2 | 100 | Merit-based |
| Interview / Personality Test | 50 | Merit-based |
| Medical Examination | — | Qualifying only |
| Total Merit Marks | 250 | Written (200) + Interview (50) |
Paper 1 — Objective Type (100 marks, 2 hours)
| Section | Questions | Marks | Medium |
|---|---|---|---|
| General Awareness | 25 | 25 | Hindi + English (bilingual) |
| Reasoning | 25 | 25 | Hindi + English (bilingual) |
| Numerical Aptitude | 25 | 25 | Hindi + English (bilingual) |
| General English | 25 | 25 | English only |
| Total | 100 | 100 |
No negative marking in Paper 1. Confirmed from the official 2026 notification and consistent with the 2019 exam pattern. Attempt all 100 questions — there is no penalty for a wrong answer.
Paper 2 — Civil Engineering Subjective (100 marks, 2 hours)
| Part | Questions | Marks Each | Total |
|---|---|---|---|
| Part A (short answer) | 5 | 2 | 10 |
| Part B (medium answer) | 5 | 8 | 40 |
| Part C (long answer) | 5 | 10 | 50 |
| Total | 15 | 100 |
Paper 2 is bilingual (Hindi and English). The difficulty level is consistently described by past candidates as comparable to UPSC Engineering Services Exam (IES) — not lower. If you are preparing for IES, this exam is good parallel preparation. If you are not, expect Paper 2 to require 3–4 months of dedicated Civil Engineering revision.
Qualifying Marks — What You Need to Pass
You must clear the qualifying threshold in each paper separately. A high Paper 1 score cannot compensate for failing Paper 2:
| Category | Minimum in Each Paper | Marks Required (out of 100) |
|---|---|---|
| UR / OBC / EWS / Ex-Servicemen | 50% | 50/100 |
| SC / ST | 45% | 45/100 |
No verified merit cut-off data (the score you actually need to make the final list) is publicly available for any ITBP AC Engineer cycle. ITBP has not published post-specific cut-offs. Given only 6 vacancies and the IES-level Paper 2, competition is intense among applicants who actually clear both qualifying thresholds.

- Solve IES previous year papers Part A and Part B — this directly builds Paper 2 speed
- Part C problems need design practice — solve 2 design problems daily in the last 4 weeks
Frequently Asked Questions
Q: Where can I download ITBP AC Engineer previous year question papers?
No official question paper PDFs are available for free download from ITBP or any government portal. The only publicly accessible source is a YouTube video from March 12, 2019, showing the actual Paper 1 and Paper 2 from the March 10, 2019 exam. Search: "ITBP AC Engineer EXAM Question Paper 1 & 2" on YouTube.
Q: Is Paper 2 only for Civil Engineering? What about other branches?
Yes — the ITBP AC Engineer post is specifically for Civil Engineers only. The B.Tech/B.E. Civil Engineering degree is the mandatory eligibility. There is no Mechanical, Electrical, or Electronics variant under this post. The ITBP AC Telecom is a completely separate post.
Q: Can I clear Paper 2 without IES preparation background?
Yes, but it requires serious preparation. Paper 2 tests all 19 Civil Engineering topics at a depth comparable to IES. Candidates who have appeared for GATE Civil or IES will find the topics familiar. Fresh graduates without exam preparation background should plan 3–4 months of dedicated Civil Engineering revision.
Q: Is there sectional cut-off in Paper 1?
No. The official notification specifies only an overall per-paper qualifying mark (50% for UR/OBC/EWS, 45% for SC/ST). There is no section-wise minimum within Paper 1. So if you score 12/25 in one section and 13/25 in another, your total of 50 still qualifies.
Q: How many vacancies are there in 2026 and how competitive is this exam?
6 posts (Civil Engineering) in the 2026 notification. With limited vacancies, a Group A Gazetted post, and a technical Paper 2 at IES level, this is a highly competitive exam among qualified civil engineers who are specifically targeting CAPF officer roles.
Paper 1 — Time Management and Attempt Strategy
Paper 1 has no negative marking, 100 questions, and 2 hours. That is 1.2 minutes per question on average. In practice, some sections are faster than others. Here is how to sequence your attempt for maximum score:
- Start with Reasoning (25 questions, 20 minutes): These have definite correct answers. Do not skip — mark and come back to anything taking over 90 seconds.
- Then Numerical Aptitude (25 questions, 25 minutes): Arithmetic is fast once you know the formulas. Skip data interpretation last — it takes reading time.
- Then General Awareness (25 questions, 20 minutes): Either you know it or you don't. Do not spend over 40 seconds per question — guess and move if unsure (no negative marking).
- Then General English (25 questions, 30 minutes): Reading comprehension needs time. Do the passage last, after all direct-answer questions.
- Last 5 minutes: Review skipped questions, verify OMR bubbling.
Because there is no negative marking, the target should be 90+ out of 100 in Paper 1. Every blank answer is a missed mark. Train yourself to make educated guesses on half-sure questions.
Paper 2 — How to Tackle 15 Questions in 2 Hours
Paper 2 is 15 subjective questions (5+5+5) over 2 hours. The biggest mistake candidates make is spending too much time on Part C (10-mark) questions and running out of time for Part A and B. Here is a smarter approach:
| Part | Questions | Marks Each | Time Budget | Strategy |
|---|---|---|---|---|
| Part A | 5 | 2 | 15 min | Definitions, formulas, one-liner answers |
| Part B | 5 | 8 | 50 min | Derivations, calculations, short design steps |
| Part C | 5 | 10 | 75 min | Full design problems — show working step by step |
For Part C, if you are stuck on a design problem, do not leave it blank. Write down the relevant IS code clause, the formula you would use, and a partial calculation. Examiners award partial marks for correct approach even if the final answer is wrong.
Most Important Civil Engineering Topics for Paper 2 — Priority Order
Not all 19 topics carry equal weight in a 15-question paper. Based on the Civil Engineering core curriculum and IES exam patterns, here is a priority order:
| Priority | Topic | Why High Priority |
|---|---|---|
| ★★★ | Design of RCC Structures (IS 456) | Largest theory base; beam/slab/column design are standard Part C questions |
| ★★★ | Structural Analysis | SFD/BMD, portal frame analysis — core civil engineering |
| ★★★ | Soil Mechanics & Foundation Engineering | Bearing capacity, consolidation — very commonly tested |
| ★★ | Fluid Mechanics (Open Channel + Pipe Flow) | Numerical problems on Bernoulli, Manning's equation |
| ★★ | Water Supply & Waste Water Engineering | Design problems on treatment units |
| ★★ | Transportation Engineering | Highway design, pavement design |
| ★ | Surveying, Building Materials, Construction Management | Shorter questions, definition-based |
Why ITBP AC Engineer is Worth Targeting — Career Angle
The post is Group A Gazetted at Pay Level 10 (₹56,100 basic). That puts it in the same tier as IPS Assistant SP and IES Officers. For a civil engineer who does not want to go the UPSC IES route (which has thousands of candidates), the ITBP AC Engineer post with just 6 vacancies and limited competition is strategically valuable. The post involves supervision of construction and infrastructure work within ITBP — which is meaningful engineering work, not just administration.
