What the BEVAE-181 Solved Question Paper June 2026 covers
BEVAE-181 Environmental Studies is the Ability Enhancement Compulsory Course (AECC) that IGNOU sets for its CBCS bachelor's learners, including BAG, BCOMG and BSCG.
The June 2026 term-end paper for this course is fully objective: 50 multiple-choice questions, one mark each, 50 marks in total, marked on an OMR sheet within 2 hours. Every question is printed in English and Hindi side by side, so learners in both mediums sit the same paper.
This year's paper runs across all four blocks. It opens with the human-made environment and the idea of possibilism, moves through trophic levels, nitrogen storage, lentic waters and estuaries, then tests forest management, hotspots, coal output and sludge gas before closing with NAPCC missions, the POPs convention, stewardship and ENVIS.
50 questions · 1 mark each · no choice · 120 minutes = about 2 minutes 24 seconds a question
Two things make this paper unusually predictable. First, 30 of its 50 questions repeat topics already set in the three earlier papers we could obtain, so three-fifths of the paper came from ground that had already been covered. Second, several question numbers have carried the same topic session after session: Question 1 has been natural versus human-made environment in all four papers, and Questions 48, 49 and 50 have been views on nature, environmental inequity and ENVIS in all three June papers. Those are four marks you can walk in knowing.
Our solved version follows the IGNOU BEVAE-181 Question Paper exactly, in printed order, so you can check a mock attempt question by question. That order matters on an OMR paper, because one misaligned bubble early on can shift every answer after it.
BEVAE-181 sample solved questions from the June 2026 paper
Questions 1 and 7 of the June 2026 BEVAE-181 paper are solved in full below, and the other 48 questions are listed as printed, with their answers only in the paid file.
These two answers were written by our subject experts from the IGNOU self-learning material. They show the format you get for every question in the full file: the correct option, the reasoning, why the other options fail and an exam tip linked to earlier papers.
Question 1 Compulsory Block 1, Unit 1 1 mark This topic was Question 1 in all 4 papers
1. Which one of the following is an example of human-made environment?
(1) Forest (2) Lakes (3) Deserts (4) Crop fields
Correct answer: (4) Crop fields
Crop fields are a human-made environment because people clear the land, choose the crop, sow it, irrigate it and harvest it. Without that constant human input the field would not exist in its present form, which is how Unit 1 of the course separates human-made surroundings from natural ones.
The other three options are natural environments. A forest develops through ecological succession without human planning, lakes form when natural basins collect rainfall, runoff or groundwater, and deserts are produced by climate, mainly very low rainfall and high evaporation. None of them needs human design to come into being.
Exam tip. IGNOU keeps rotating this idea, and it keeps putting it at Question 1. June 2024 asked you to pick the natural environment, June 2025 asked for a human modified one, and June 2026 asks for a human-made one. In every version, separate what nature produced on its own from what people deliberately created or reshaped.
Question 7 Compulsory Block 1, Unit 2 1 mark Cycle reservoirs set in 3 of 4 papers
7. The main reservoir of nitrogen in the biosphere is:
(1) Oceans (2) Rocks (3) Atmosphere (4) Organisms
Correct answer: (3) Atmosphere
Nitrogen follows a gaseous cycle, and the atmosphere is its main reservoir in the biosphere. About 78 per cent of air by volume is nitrogen gas (N2), a stock far larger than the nitrogen moving through soil, water and living things at any moment.
Most organisms cannot use N2 directly. Nitrogen-fixing bacteria such as Rhizobium in legume root nodules, cyanobacteria such as Anabaena and Nostoc, and lightning, convert it into ammonia and nitrates that plants absorb. Animals take nitrogen in by eating plants, decomposers return it to the soil as ammonia, and denitrifying bacteria release N2 back into the air.
Why not the others? Oceans hold dissolved nitrogen compounds but are not the main store, rocks and sediments are the reservoirs of sedimentary cycles such as phosphorus and sulphur, and organisms hold nitrogen only for a while in their proteins and nucleic acids before decomposers release it.
Exam tip. Sort every nutrient cycle into gaseous (carbon, nitrogen) or sedimentary (phosphorus, sulphur) before you answer. IGNOU asked for the sulphur reservoir in June 2024 and a sedimentary-cycle question in December 2021.

How to work through 50 questions in 120 minutes. You get 2 minutes 24 seconds a question, and most BEVAE-181 questions take under a minute, so the spare time belongs to the few long ones. Do two passes. On the first, answer every one-line question straight off and leave the statement-type questions — Q14 on aquifers, Q16 on tropical rain forest and Q37 on incineration cost, where you have to read and compare four full sentences. Come back to those on the second pass with the time you have banked. A wrong answer costs you that question's mark and nothing more, so never leave a bubble blank: a considered guess between two options is worth half a mark on average, and an empty row is worth nothing.
BEVAE-181 Environmental Studies block and unit wise syllabus
BEVAE-181 Environmental Studies is taught through 4 blocks and 14 units in IGNOU's self-learning material, and the June 2026 paper draws questions from every block.
The table maps each unit to topics that IGNOU has actually examined in its papers, and the last column counts how many of the 50 June 2026 marks came from that unit. If you want detailed notes for each unit beside the solved paper, our BEVAE-181 Study Material follows the same block order.
| Block | Unit | Topics examined in IGNOU papers | June 2026 marks |

| Total | 50 | ||
Unit 7 on energy resources was the single busiest unit, with six marks on its own: renewable resources, conventional energy, world coal output, per-capita demand, the biomass gasifier and sludge gas. Unit 3 on major ecosystems came next with five. At the other end, Unit 5 on forests and Unit 14 on ethics gave only two marks each. Seven of the fourteen units — Units 3, 6, 7, 8, 9, 12 and 13 — between them carried 31 of the 50 marks, so half the course supplied nearly two-thirds of the paper.
Block 4 is the one learners often skip, yet it holds the law, health and ethics questions that IGNOU sets in almost every session, and in June 2026 the last three questions of the paper came straight out of it. Units 12 to 14 are short, so a single evening on them protects several easy marks.
BEVAE-181 question paper pattern and marks distribution
The BEVAE-181 Question Paper for June 2026 has 50 compulsory multiple-choice questions of 1 mark each, answered on an OMR sheet in 2 hours.
Each question has four options with one correct answer. The paper also allows a fifth response: if you find that none of the four options is correct, you write 0 and mark column 0. Use it only when you are certain, because a wrong 0 costs the mark like any other wrong bubble.
| Block | Units | Question numbers in June 2026 | Questions | Marks |
|---|---|---|---|---|
| Block 1: An Introduction to Environment and Environmental Studies | 1 to 3 | 1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 16 | 11 | 11 |
| Block 2: Natural Resources | 4 to 7 | 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 | 15 | 15 |
| Block 3: Environmental Issues and Concerns | 8 to 11 | 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 | 14 | 14 |
| Block 4: Protecting Our Environment: Policies and Practices | 12 to 14 | 3, 42, 43, 44, 45, 46, 47, 48, 49, 50 | 10 | 10 |
| Total | 14 units | 1 to 50 | 50 | 50 |
Block 2 carried the most marks at 15, Block 3 came next at 14, and the paper ran broadly in block order with one exception: Question 3 on demographic transition belongs to Block 4, Unit 13, even though it sits among the Block 1 questions. Everything from Question 42 onwards is Block 4.
Earlier sessions follow the same 50-question format, and you can compare them in our IGNOU Previous Year Question Paper collection before attempting the June 2026 paper under timed conditions.
Most repeated BEVAE-181 topics across official IGNOU papers
Across the four official BEVAE-181 papers we could access, December 2021, June 2024, June 2025 and June 2026, eight topics appeared in every single paper.
We read each paper from IGNOU's own websites and matched the June 2026 questions against the earlier three. The count below is out of those four papers only. We could not obtain official copies for June 2022, December 2022, June 2023, December 2023, December 2024 or December 2025, so this is not a five-year claim.
Topics marked 4 of 4 are the safest revision targets, and the same pattern shapes our IGNOU Solved Guess Paper lists for other courses. The table names topics only; it does not give any answer.
| Topic | June 2026 question | Earlier official papers | Papers with this topic (of 4) |

| NBA and biodiversity law | Q43 | Jun 2024 Q42 | 2 |
| Genetic versus behavioural health conditions | Q46 | Jun 2024 Q45 | 2 |
Thirty of the fifty June 2026 questions are in that table. In other words, three-fifths of the paper tested topics already set in the three earlier papers we have, and the remaining twenty were new to this window. On an objective paper that is the strongest argument for working through old papers rather than reading the units end to end.
Some question numbers barely move. Reading down the table, the June papers line up almost position for position:
- Question 1 has been natural versus human-made environment in all four papers, December 2021 included.
- Question 2 has been determinism or possibilism in December 2021, June 2024 and June 2026.
- Question 8 has been forest types identified by their trees in June 2024, June 2025 and June 2026.
- Questions 48, 49 and 50 have been views on nature, types of environmental inequity and ENVIS centres in June 2024, June 2025 and June 2026 — the same three topics in the same three positions for three years.
Several more sit one place later in June 2026 than in the two previous June papers — trophic levels moved from Q5 to Q6, the ozone unit from Q39 to Q40, hazards from Q46 to Q47, waste treatment from Q35 to Q36 — as though one extra question was inserted early and pushed the middle of the paper down by one. The opening and the closing stayed locked.
The practical use is simple. If you prepare Unit 1 on natural and human-made environment, Unit 3 on forest types, Unit 12 on ENVIS and Unit 14 on ethics and inequity, you are walking in with five or six questions whose topic you can predict before you turn the page, including the last three. December sessions scramble the order — December 2021 put ethics at Q5, inequity at Q4 and ENVIS at Q6 — so this is a June-session pattern, not a rule.
How our BEVAE-181 answers are written and checked
Every answer in our BEVAE-181 file gives the correct option number, a short reason and the SLM unit it comes from, written by Prateek Talwar, Academic Head, and reviewed by Sheetal Kirola.
Each answer is checked against the official BEVAE-181 self-learning material published on eGyanKosh, not against third-party guides. Where an option rests on a figure, a year or a place, the explanation states it plainly so you can verify it in the unit.
Because this is an OMR paper, the file is laid out for fast checking: question number, correct option in bold, then two to four lines of reasoning. Where a question repeats a past topic, the answer points to the earlier session, so you see the pattern while revising.
Question text is set out as it appears in the official paper, including its numbering and option order. Where the printed paper misspells a name or breaks a sentence, we keep the printed words and give the correct form in square brackets, because the OMR sheet is marked on option numbers and you should be able to match our file to your paper line by line.
A second reviewer reads every answer before release. The review looks at three things: the option number, whether the reason matches the unit text, and whether the wording would make sense to a first-year learner reading it the night before the exam.
BEVAE-181 solved file index for all 50 questions
The BEVAE-181 solved file covers all 50 questions of the June 2026 paper: 2 are answered on this page (Q1 and Q7) and 48 are answered only in the full file.
BEVAE-181 is a theory course with no practical or record work, so instead of a practical file index we list every question with its unit. If you are in BA General, the same index helps you plan revision alongside the BAG Question Paper set for your other courses.

Programmes that include BEVAE-181 Environmental Studies
BEVAE-181 Environmental Studies is a compulsory AECC in IGNOU's CBCS bachelor's programmes, so BA, B.Com and B.Sc learners all sit the same objective paper.
The course is studied in the IGNOU Bachelor of Arts (General) (BAG), Bachelor of Commerce (General) (BCOMG) and Bachelor of Science (General) (BSCG). It also appears in BA Honours programmes in English (BAEGH), History (BAHIH), Political Science (BAPSH), Sociology (BASOH), Psychology (BAPCH) and Public Administration (BAPAH).
The June 2026 paper header names B.A., B.Com, B.Sc and BAVMSME, the vocational degree in Micro, Small and Medium Enterprises. On eGyanKosh the same four blocks are filed under several schools, including the School of Sciences for BSCG, the School of Management Studies for B.Com and BBA, and the School of Computer and Information Sciences for BCA.
That makes BEVAE-181 the widest-reaching course on this site: twelve programmes in all, more than any other IGNOU paper we solve. Because every one of them uses the same paper, the solved file is identical whichever programme you are enrolled in. Only your roll number and programme code on the OMR sheet change.

How many questions are in the BEVAE-181 June 2026 question paper?
The BEVAE-181 June 2026 paper has 50 multiple-choice questions, and every question is compulsory. Each carries one mark, giving a maximum of 50 marks, and the time allowed is 2 hours. Every question has four options with one correct answer, and if you feel none is correct the instructions ask you to write 0 and mark column 0 on the OMR sheet.
Is the BEVAE-181 Environmental Studies term-end exam objective or descriptive?
It is fully objective. The June 2026 BEVAE-181 paper, like the June 2024 and June 2025 papers, asks 50 one-mark multiple-choice questions that are answered only on an OMR sheet. There are no long answers in the term-end exam. Descriptive writing appears in the tutor-marked assignment instead, which is a separate part of your assessment for this course.
How should I use the 2 hours in the BEVAE-181 exam?
You have 2 minutes 24 seconds a question, and most BEVAE-181 questions are one-liners that take well under a minute, so work in two passes. Answer every short question on the first pass and skip the statement-type ones where you must read and compare four full sentences, such as the aquifer, tropical rain forest and incineration questions in the June 2026 paper. Come back to those with the time you have saved, and fill every bubble before you hand in the sheet, because a blank row scores nothing while a considered guess between two options is worth half a mark on average.
Which BEVAE-181 topics repeat most often in official IGNOU papers?
In the four official papers we checked (December 2021, June 2024, June 2025 and June 2026), eight topics appeared every time: natural versus human-made environment, trophic levels, forest types, the ozone layer, natural hazards, views on nature, environmental inequity and ENVIS. Possibilism, Joint Forest Management, hotspots and international conventions appeared in three of those four papers. Thirty of the fifty June 2026 questions came from topics already set in the earlier papers.
Do BEVAE-181 questions appear at the same numbers each session?
In the June papers, several do. Question 1 has asked about natural versus human-made environment in all four papers we checked, Question 8 has asked about forest types in the last three June papers, and Questions 48, 49 and 50 have been views on nature, environmental inequity and ENVIS in June 2024, June 2025 and June 2026 alike. December sessions scramble the order, so treat this as a June pattern rather than a rule, but it does mean the last three questions of a June paper are worth preparing specifically.
Which BEVAE-181 unit carried the most marks in June 2026?
Unit 7 on energy resources, with six of the fifty marks: renewable resources, conventional energy, world coal output, per-capita energy demand, the biomass gasifier and sludge gas. Unit 3 on major ecosystems came second with five. By block, Block 2 on natural resources carried 15 marks and Block 3 on environmental issues 14, while Block 1 carried 11 and Block 4 carried 10. Every one of the 14 units produced at least two marks.
Does BEVAE-181 Environmental Studies have a practical file or record work?
No. BEVAE-181 is a theory course, and IGNOU's assignment booklet lists one tutor-marked assignment as its only continuous evaluation, with no practical file or lab record. That is why this page gives a solved file index instead, showing all 50 June 2026 questions, the unit each one comes from and whether it is answered here or only in the full file.
Which IGNOU programmes include BEVAE-181 Environmental Studies?
BEVAE-181 is a compulsory Ability Enhancement course across IGNOU's CBCS bachelor's programmes. It is studied in BAG, BCOMG and BSCG, and in BA Honours programmes such as BAEGH, BAHIH, BAPSH, BASOH, BAPCH and BAPAH. The June 2026 paper header also names BAVMSME, and eGyanKosh lists the same course under BBA and BCA as well, which makes it the widest-reaching paper on this site.
How is BEVAE-181 Environmental Studies assessed apart from the term-end exam?
BEVAE-181 also has one tutor-marked assignment, which carries 30 per cent weightage in your final result according to IGNOU's assignment booklet. The assignment is set for 100 marks in two parts, A and B, and you need 35 per cent to pass it. You must submit it on time to be eligible for the term-end exam, which carries the remaining weightage.
Who wrote and reviewed the BEVAE-181 solved answers?
The BEVAE-181 answers were written by Prateek Talwar, Academic Head of Unnati Educations, and reviewed by Sheetal Kirola before release. Every option was checked against the official self-learning material on eGyanKosh rather than against other websites, and each answer carries the unit reference so you can verify it yourself.
