IB MTS Exam Pattern 2026: Tier 1, Tier 2 and Marking

The IB MTS exam pattern has two written stages: a one-hour online objective test (Tier I) and a one-hour descriptive English test (Tier II). The Intelligence Bureau, under the Ministry of Home Affairs, uses this pattern to recruit Multi-Tasking Staff (General) at the Class 10 level, and only Tier I marks decide the final merit list.

This page explains the pattern from the official IB MTS (General) Exam 2025 notification: the section-wise marks, negative marking, minimum qualifying marks, how candidates are shortlisted for Tier II and how the final merit is prepared. It also turns those numbers into a practical time and scoring plan, which matters more here than in most exams because you have only 36 seconds per question on average.

IB MTS Exam Pattern at a Glance

There is no interview and no physical test for IB MTS (General) under the 2025 notification.

Tier I Exam Pattern

Tier I is a computer-based test of 100 multiple-choice questions, one mark each, to be finished in one hour. All four sections share the same hour; the notification does not set separate sectional time limits.

Exam Centres and Admit Card

In the 2025 cycle, candidates chose five exam centre options while applying. The notification says admit cards and call letters are sent to the registered email ID, so keep that inbox active and check spam folders around exam time.

Section-Wise Question Types

The notification gives section names only. Based on the Class 10 level of the post, these are the question types to expect, with a realistic time target for each.

These targets add up to about 50 to 55 minutes, which leaves a few minutes for review. If your mock times are far above them in one section, that section is where practice will add the most marks.

Marking Scheme and Negative Marking

• Correct answer: 1 mark.

• Wrong answer: One-quarter of a mark is deducted.

• Unattempted question: Zero; no deduction.

• Marked for review: The notification warns about how marked-for-review questions are treated. Read the instructions on your admit card and the exam screen, and make sure every answer you want counted is saved as a final answer.

• Normalisation: The notification says Tier I scores are normalised, which matters if the exam runs in more than one shift.

In practice, four wrong answers wipe out one correct answer. A blind guess among four options is roughly break-even, but a guess after removing two wrong options works in your favour.

Minimum Qualifying Marks in Tier I

The notification sets the following minimum Tier I marks. Candidates must reach these to be considered for Tier II.

Ex-servicemen and PwBD candidates are considered within their own category. IB can raise these marks based on performance and the number of vacancies. From the candidates who clear them, about 10 times the number of vacancies are shortlisted for Tier II, so the effective shortlisting score is usually much higher than these floors.

Tier II Exam Pattern

Tier II is taken only by candidates shortlisted from Tier I. It is a written test, not an objective one.

The notification also says Tier II may not be held at every centre, and centres may be combined, so you may need to travel to a different city than for Tier I.

What the Pattern Means for You

Numbers in a pattern table are only useful once you turn them into decisions. Here is what the IB MTS structure implies.

Marks per Minute

With 100 questions in 60 minutes, you have 36 seconds per question on average. General Awareness questions take 10 to 20 seconds when you know the answer and cannot be worked out when you do not. That makes General Awareness the place to bank time for maths and reasoning.

Where the Marks Sit

• General Awareness, 40 marks: The single largest block. A strong score here can make up for a weak section elsewhere.

• Maths, Reasoning and English, 20 marks each: Smaller sections, but reasoning and English often give the highest accuracy with practice.

• Tier II, 0 merit marks: It only needs 20 out of 50, but it is pass-or-fail for your selection.

The Cost of a Wrong Guess

Each wrong answer costs a quarter mark. Suppose two candidates both know 60 answers. One attempts only those and scores 60. The other also guesses 20 questions blindly, gets about 5 right and 15 wrong, and ends near 61.25, a gain of barely one mark for a lot of risk. Guessing pays only when you can rule out options.

No Sectional Cut-Off, but No Free Pass

The notification sets an overall minimum, not section-wise minimums. You can carry a weaker section, but since merit is overall, every section still counts.

How the Final Merit List Is Prepared

1. Tier I scores are normalised where needed and checked against the minimum qualifying marks.

2. About 10 times the vacancies are shortlisted for Tier II, SIB-wise and category-wise.

3. Tier II is checked for qualification at 20 out of 50.

4. Merit is prepared on Tier I marks among those who qualify Tier II, separately for each SIB and category, with a waiting list.

5. Ties are broken by age: The older candidate ranks higher. If dates of birth also match, alphabetical order of names, starting with the first name, decides.

A worked example: two OBC candidates in the same SIB score 74 and 71 in Tier I. Both clear Tier II, one with 38 and one with 22 out of 50. The candidate with 74 ranks higher, because Tier II marks do not change the order. If the second candidate had scored 19 in Tier II, they would be out of the list despite a strong Tier I score.

Preparing for Tier I and Tier II Together

Many candidates prepare only for Tier I and then rush Tier II in the gap after the result. In the 2025 cycle, Tier II was reported about three months after the Tier I result, which sounds like plenty of time. The problem is that writing skill improves slowly, and the same weeks often go into waiting and travel planning.

• Share the English base: Grammar and vocabulary study for Tier I English directly supports Tier II writing.

• Write once a week from the start: One 150-word paragraph and one comprehension answer a week is enough before Tier I.

• Switch fully after Tier I: Once you have taken Tier I, move to daily timed writing until Tier II.

• Get feedback: Ask a teacher or a strong English reader to mark your paragraphs for grammar and clarity, since self-checking misses repeated errors.

Time Management and Exam-Day Strategy

Practise a fixed order in mocks so the real exam feels routine. One approach that suits most candidates:

• Use two rounds: In the first round, answer everything you can do quickly. In the second, return to the slower questions.

• Cap each question: If a maths question passes 60 seconds without a clear path, move on.

• Plan Tier II on paper: In the descriptive test, spend two minutes planning the paragraph and three minutes proofreading at the end.

The fastest way to make this timing automatic is full-length practice. You can take timed IB MTS mock tests on Testkart in the Tier I pattern and use the section-wise time and accuracy report to see which section is eating your minutes. Repeating the same order in every mock means exam day holds no surprises.

Common Mistakes Linked to the Pattern

• Spending too long on maths early: Twenty maths questions can easily take 25 minutes if you start with them. Attempt them after the faster sections.

• Guessing to "use" every question: With a quarter-mark penalty and no reward for attempts, a blank is better than a blind guess.

• Treating the minimum marks as the goal: Clearing 30 out of 100 rarely gets a UR candidate into the Tier II shortlist when only about 10 candidates per vacancy are called.

• Skipping full-length practice: Sectional tests build skill, but only full one-hour mocks teach you how to split time across four sections.

• Neglecting presentation in Tier II: A descriptive answer is read and marked by an evaluator. Clear paragraphs, neat handwriting if the test is on paper, and a tidy layout make your answer easier to evaluate.

Key Changes and Older-Page Warnings

• No interview: Some older pages describe a Tier III interview for IB MTS. The 2025 notification has Tier I, Tier II, document verification and medical examination only.

• Tier II is descriptive English: It is not a local language test. Pages that mix MTS with the Security Assistant exam sometimes show the wrong Tier II.

• Minimum marks are floors: Older pages sometimes present the minimum qualifying marks as the cut-off. The actual shortlisting score is decided after the exam.
