INMO 2020 Exam Pattern

Pattern of Questions INMO

While preparing for the exam, we all compete with ourselves and our colleagues and try to exceed our own expectations. For that, we need to first familiarize ourselves with the best and the newest content available in the market. Also, we need to be functional and interactive with how the exam paper will turn out to circumvent any surprises. The optimum way is to review the INMO previous year question papers offered by Vedantu. When the exam is as important and prestigious as the Indian National Mathematical Olympiad, it becomes even more important.

Maths is a subject that can never be learned and there are always multiple questions to be practiced so why not review the questions which have been asked in the past. The previous year question papers give practical experience of how the pattern of the question actually is. You should also keep in mind that it is a national level exam so you are competing with other students throughout the country. Here at Vedantu, we provide INMO previous year question papers for the last 5 years in order to help you in preparation. These papers are issued along with the proper explanation of each answer.

INMO Previous Year Question Paper With Solution

Practicing previous year questions appears to be a worthwhile study to understand the INMO exam patterns, type of questions, and also the marking scheme. Students can get an opportunity to acquire higher problem-solving skills to examine the INMO previous year chapter wise question paper. This set includes the solution for the most important topics such as Inequalities, Probability Theory, permutation and combination, Elementary Combianantric, Quadratic equations and expressions, and many more included in the INMO syllabus. Students can freely download the previous year’s question papers issued by Vedantu by clicking the link given below.

What is INMO?

INMO or Indian National Mathematics Olympiad is the second phase of the hierarchy to qualify for the International Mathematics Olympiad (IMO). The Indian National Mathematics Olympiad exam is a Mathematics Olympiad in which students who have qualified Regional mathematics olympiad are eligible to participate.

INMo is organized and conducted each year under the supervision of the Homi Bhabha Center for Science Education (HBCSE). It is an organization that is responsible for organizing the Olympiad exam across the country. High school students get an opportunity to participate in the International Mathematics Olympiad (IMO), the world championship in Mathematics after qualifying INMO exam organized by (HBCSE).

INMO Admit Card 2021

INMO admit cards will be issued in the month of January and the students can download the card online by visiting HBCSE official website. The INMO admit cards are not sent by post and the students without carrying the admit card will not be allowed to appear in the exam. Apart from the INMO admit card, the students also have to carry the school photo ID card.

INMO Reference Books

There are multiple reference books for INMO exams. For beginners, a Mathematical circle by Dimitri Fomin is suggested. This is an excellent book to start your Olympiad exam journey. Even the students having limited knowledge, it is suggested to read this book as it provides good information about some concepts.

An Excursion in Mathematics is a comprehensive book for the INMO exam. This book has all the content that is required to prepare for INMO exams. All INMO qualifiers get this book as an award.

For an advanced reader, Problem- Solving Strategies by Arthur Engel is another excellent book. It aims to provide information about the concepts used to solve the problems. Each chapter is dedicated to one specific technique and covers some problems directly from INMO. This book is also awarded to INMO qualifiers. Apart from these books, there are various other books for different subsections such as number theory, Geometry, Algebra, and Combinatorics.

FAQ (Frequently Asked Questions)

Q1. How Many Questions do I Need to Solve in INMO to get Selected?

Ans: The basis for INMO qualification is the rank of the student in the region and not the number of questions you answer. Even though you lack to solve good no. of questions, there is always a good chance of cracking through as it ultimately depends on how the other students performed. More so, you can also check the cut-off scores of different regions from previous INMO papers to have a fair idea.

Q2. How Would I Benefit Academically by Enrolling in INMO?

Ans: With the current education scenario, excellent scores in national level senior Olympiads is far more valuable for future admissions than marks in high school or intermediate. The chief role of outstanding performance in Olympiads like INMO is for postgraduate admissions is that it renders a reflection of talent at a young age. Good performance in INMO is particularly helpful to students seeking out for admission in postgraduate admissions courses like Math, Stats, and C.S. Having said that, don’t confuse this as your guaranteed admission this is just a turning point. A Graduate School, while accounting for a student’s application for admission, is looking at the student’s just finished stage of (undergraduate studies) and the initiatives, achievements, and background procured in this most recent stage.

Q3. What is the Marking Scheme in INMO? How Many Questions do we Need to Solve to get Through RMO?

Ans: The RMO test paper is subjective and partial marks are allotted to the partially correct or incomplete answers written. The answers are assessed on the basis of correctness only. The Foundation already has an answer script prepared which is the RMO answer key. They release the key a few weeks after the date of the INMO examination and before announcement of the results. However, if your solution follows a logical step by step procedure and you’ve got the proof/answer right, you are allotted marks even if your solution differs from theirs.

The number of questions to solve appropriately to ensure clearance differs from test paper to paper, but generally, if you’re sure of scoring 50% of the total marks, you can contemplate yourself safely through.

Q4. Is RMO Tougher than JEE (Adv)?

Ans: RMO is supposed to be cleared only by 300–500 students at most, whereas JEE is meant to be cracked by a minimum of 10000 candidates. That said, only a selective few can really solve RMO problems. Moreover, RMO is a regional level mathematical competition exam but JEE is a national level exam taken by 1.7 million students. You won’t find any trigonometric summation or Taylor series in RMO; instead you’ll see questions that deal with the most abstract concepts and require higher levels of analytical thinking and creativity which isn’t really required in JEE.

RMO aims at mathematical thinking whereas the JEE aims at capturing the smartest technical minds of our country, thus both are different. RMO paper contains 6 questions which have to be solved in 3 hours while JEE has 30 questions to be solved in 60 minutes. And it would be insignificant to say if one is tougher or easier than the other.
