I want to ask all of you that how can we compare the problem level of RMO and Brilliant.org. Means I want to know whether problems on Brilliant are of the level as that of RMO, specially Level 5 problems.Or they are of much higher or equivalent level as compared to RMO.

TopNewestYes, Level 4 problems touch RMO stage one level, The level five problems that are worth 180+ points are eligible to be asked in RMO-2. The 300 point problem, though, is abstract and chances are that such a problem won't be asked till INMO. Source-Gave RMO thrice., got 102/102 last year. – Arshdeep Duggal · 4 years, 1 month ago

Note that if the competitions require actual proof writing, it can be much harder than simply guessing a numerical answer and being extremely lucky. Of course, if you also include how we award points for your submitted solutions, then this begins to be similar to proof questions.

I did "An excursion in Mathematics" and Arihant's "Mathematical Olympiads" by Rajeev Manocha. The latter stresses on quantity rather than quality so you need not do all of it The former is the best one in the market, but no ordinary level student can do it. I started doing it in 9th but kept leaving it as it seemed really tough. And yes, make sure you solve a standard +1 maths book before going into Olympiad stuff.Topics like coordinate geometry give you an unparalleled advantage, I solved both the geometry questions last year using coordinates. And if you can do calculus, it is very very very helpful. I don't know why people discourage it, but it was one of my strengths and I actually solved a number theory question in level 1 using calculus! Most important-Cover +1 first, even R.D Sharma is great. And then you can jump into excursion and other books And no, no crash course."Crash course" is a synonym for minting money in the coaching industry. Again, do +1 Maths from a standard book first. Me and my friends did just that and we crashed RMO!!If you are 16,I would strongly advise not to prepare for RMO by compromising your preparation for IIT-JEE. Keep that in mind. It has happened to me, but I got away. For any further queries, feel free to mail me at gdspoce@gmail.comLog in to reply

I never trashed R.M. I just said it focuses on quantity. It is a good book for practice.But the concepts should not be learnt from there, Excursion is a great book for that.Log in to reply

The geometry section of Pre-college is very useful................but if you want to go for problems along with solutions the arihant book may do the job for you as it contains previous yr questions of RMO nd INMO + solutions, but there are some printing mistakes and some logical ones too. Be sure to rectify them. Precollege also has a variety of questions and the style of writing is exquisite. ................Happy reading :)).......By the way what is"OCSC"??Log in to reply
