The IOE Entrance Examination: Pattern, Weightage and Strategy

This is the one page to read before you start. It states the verified facts of the IOE B.E. / B.Arch. entrance examination, then the strategy that follows from them. Where a fact is our estimate (for example the split of questions between chapters) it says so.

1. What the examination is

The Institute of Engineering (IOE), Tribhuvan University admits students to Bachelor of Engineering (B.E.) and Bachelor of Architecture (B.Arch.) programmes through one common entrance examination. It is the gateway to the five constituent campuses (Pulchowk, Thapathali, Purwanchal (Dharan), Paschimanchal (Pokhara), Chitwan) and to the affiliated colleges that use the same list.

Not published by IOE: how the 60 + 40 questions split between the four subjects, and how many questions each chapter gets. Most third-party sources give Maths 20 + 15, Physics 14 + 13, Chemistry 14 + 8, English 12 + 4, and this is the only split that sums correctly to the booklet's Section A and B headers (60 × 1 and 40 × 2) and to the subject marks 50 / 40 / 30 / 20. (One site lists Mathematics as 14 + 18; its own table then totals 54 one-mark and 43 two-mark questions instead of 60 and 40, so it cannot be right.); the NEBians books and model papers use exactly this split and say so. The chapter-wise question numbers in this book are our estimate, not an official table.

Pass mark. There is no fixed published pass mark; IOE sets a minimum percentage for each year and only candidates at or above it enter the merit list. Past years' qualifying scores reported by third parties are in the region of 50–55 marks of 140 (35–40 %); treat that as a floor, not a target. Scholarship (regular) seats and full-fee seats are ranked by entrance score.

Eligibility (check the current notice): a pass in 10+2 Science (Physics, Chemistry, Mathematics) or A-level or an engineering diploma, with at least 45 % of the total marks in Physics, Chemistry and Mathematics taken together in Class 11 and 12 and, for NEB candidates, at least a C grade in each of those subjects in the final grade sheet (per the 2083/84 notice; equivalents apply for A-level and diploma).

2083 cycle (as published July 2026). Online form at entrance.ioe.edu.np; examinations in Shrawan 2083 (11–14 Shrawan at Pulchowk and the other three centres, in several shifts); admit card downloaded and printed in colour; original identification document carried to the hall. Reports in June 2026 mentioned a different format and fee in an earlier draft; the final notice and the 2083 booklet both state 100 questions, 140 marks, 10 % negative marking — always confirm the date, fee and pattern on the IOE entrance portal before applying.

2. What it tests

The paper tests the Grade 11–12 science syllabus at entrance depth: IOE's own 6-page "Detail Syllabus 2083" is the legal syllabus (a copy is included in the downloads). It is short: Mathematics 7 areas, Physics 6, Chemistry 3, English 4. The model questions printed in the official booklet show the level:

• Section A (1 mark): single-step — one identity, one standard result, one substitution. Example: the value of k for which one root of 3x^2+7x+6-k=0 is zero.
• Section B (2 marks): two or three steps. Example: the projection of one vector on another; the depth at which a rubber ball's volume falls by 1 %; copper deposited by 2 faradays.
• English: concord and tense, prepositions, word stress, initial vowel sound, one comprehension passage.

3. How the marks are distributed (this book's estimate)

Reading the table: Mathematics plus Physics are 90 of 140 marks (64 %). A candidate strong in Maths and Physics who is accurate in Chemistry and English will clear the qualifying line comfortably; a rank in Pulchowk's civil / computer / electronics programmes needs a high score in all four.

4. Strategy that the negative marking dictates

Penalty is 10 % of the question's marks, so a guess among four options has a small expected cost compared with its expected gain:

• Random guess, 1 mark: expected value =\tfrac{1}{4}(1)-\tfrac{3}{4}(0.1)=+0.175.
• Random guess, 2 marks: =\tfrac{1}{4}(2)-\tfrac{3}{4}(0.2)=+0.35.
• Eliminate two options (50 : 50): +0.45 (1 mark) and +0.9 (2 marks).

So on this paper you should answer every question where you can eliminate at least one option, and rarely leave blanks. Unlike CEE (−0.25), the IOE penalty is small. (If you can eliminate nothing, a guess is still mildly positive; time is the real cost.)

Time plan (120 min / 100 questions): 1. 0–45 min: Section A (60 × 1). Do English first (12 questions, 10 minutes), then Chemistry facts, then Physics and Maths one-liners. Skip anything that needs more than 90 seconds and mark it in the on-screen palette. 2. 45–105 min: Section B (40 × 2). Maths first while you are fresh, then Physics numerics, then Chemistry and English. 3. 105–120 min: return to skipped questions; use elimination; check the units of your last few numerical answers.

Technique list - Substitute the options into the question (test values) when a direct solution is long — especially in algebra, trigonometry and coordinate geometry. - Use dimensional analysis and limiting cases (set x\to0, \theta=90^\circ) to kill wrong options in physics. - In chemistry numericals, convert to moles first; in physics numericals write the formula and units before the numbers. - In English, read the sentence aloud in your head: concord and tense errors "sound" wrong. - On a computer-based test there is no rough sheet on the screen — carry the permitted pen and paper rules from the admit card; practise mental arithmetic with \sqrt{2}=1.414, \sqrt{3}=1.732, \pi=3.14, \ln2=0.693, g=9.8 or 10.

5. A 12-week plan

Daily rhythm: 90 minutes of theory, 90 minutes of MCQs, and at the end of each week one timed 40-question set (60 minutes) built from the Practice questions of that week's chapters. Keep an error log — the reason you lost each mark (formula, unit, arithmetic, misread, guess) — and review it every Sunday. After 3–4 weeks the log will show you which of those five causes you actually have.

6. How to use the books

1. Read the chapter's "What the paper asks" box, then the theory, then the Formula and fact sheet.
2. Do Set A (recall) without looking; Set B (understanding) and Set C (application) with a clock.
3. Every question has an explanation — read it even when you were right.
4. After each subject finish a model paper section; after all four, take a full paper under exam conditions (120 minutes, no pauses, mouse only if you can).
5. Honest numbers: the questions here are original practice written to the official syllabus. No question here claims to be a past question. IOE publishes model questions in the booklet, not past papers; the nineteen published model questions informed the style of these books.

7. Common mistakes

• Treating Mathematics as the only subject: Physics + Chemistry + English are 90 marks.
• Leaving English until the last week: it is 20 marks and the fastest to improve.
• Using g=9.8 in one question and 10 in another without reading the stem.
• Forgetting that IOE answers come as exact forms (\sqrt{3}/2, \frac{\pi}{4}): do not convert to decimals until the end.
• Losing marks on the negative-marking arithmetic by changing many answers in the last minutes; change an answer only when you find a concrete error.

8. After the exam

The Entrance Examination Board publishes the list of successful candidates; constituent campuses run admission and counselling; scorecards must be downloaded within the stated period after the result. Regular (scholarship) seats follow the Government of Nepal's scholarship rules; the fee for the four-year B.E. programme for regular students in 2083/84 was reported as roughly NPR 66,000 in total and about NPR 586,000 for full-fee students — confirm every amount on the official notice.
