Hello Aspirant,

The INMO is not like typical exams, which require students to answer several questions in a limited amount of time. Its questions necessitate smart and serious thinking. The tasks are rigorous mathematical in nature, rather than the application-based issues that most students are accustomed to. It's evident that visualising the complete solution at once is really tough.

Following are some reference books for these examinations:

1. For beginners, Mathematical Circles by Dimitri Fomin
2. An Excursion in Mathematics is a comprehensive book.
3. Challenges from the Olympiads by C.R. Pranesachar, S.A. Shirali, B.J. Venkatachala, and C.S. Yogananda
4. Problem Primer for the Olympiad by C.R. Pranesachar, B.J. Venkatachala, and C.S. Yogananda

It's all about taking little actions and gradually constructing the solution. The complex-looking answer is made up of a series of simple stages. As a result, while the problems and their solutions may appear to be insurmountable at first, they are very much solvable. The solution will not come to you right away when you see the problem. To begin, you must fully appreciate the issue. Then try to come up with a strategy for resolving the situation. Every solution is made up of a collection of concepts and ideas.

RMO can benefit from the following suggestions:

There is no defined pattern for the RMO, however there is a prescribed syllabus. Concentrate on understanding the concepts and developing the fundamental abilities needed to solve problems and prove theorems. In fact, the first few days of study should be spent avoiding tough tasks and thoroughly reviewing the content.Take at least 1-2 hours per day for at least five to six months to practise maths. As many various types of problems as feasible should be attempted. If you can quickly solve practically all of them, rest confident that your issue selection has to be improved. While working on various tasks, attempt to identify which topics you excel in and which you struggle with. Combinatory, geometry, and number theory must be your primary focus. Solving previous year's papers will help you become familiar with the test's pattern and structure, as well as give you an idea of the required standard. Although memory isn't one of the RMO's most significant talents, having the key theorems and findings at your fingertips will save you time and effort. Get warned and read more carefully if a problem appears to be too simple. Because Olympiad issues are notorious for their deception, the entire test will be a delightful fight.

I hope this helps.

Good Luck
