# RMO v/s Brilliant.org

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.

Yes, 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.

Typically, harder questions will have a higher point weightage. Your approach of looking at the point weightage of each problem would be a better gauge, since each level gets quite a wide range of problems in terms of difficulty.

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 don't know much about the specifics of RMO/INMO, so won't be able to comment on their relative difficulties.]

@Master - you can guess the level of difficulty of RMO and INMO from here

I was eligible for OCSC but did not go as it would hamper my JEE preparation.(I just gave JEE-2013).Feel free to send any queries to gdspoce@gmail.com. I am happy to help.

You are which year , INMO awardee? As , i don;t remember your and arshdeep.D name in the list :)

@Arshdeep D - please can you tell from which book did you prepare for RMO and did you took any type of coaching like the resonance crash course or etc (there are many). . It will really help me a lot. Thanks in advance

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.com

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.

Why do you say ::

Don't prepare for RMO compromising IIT PREP

- 1 year, 6 months ago

wow!! u r such an intelligent guy!!!!!!! do u go for any kind of coaching???

- 5 years ago

Yes, I used to, but not exclusively for Olympiads. I am in IIT Bombay right now.

You can try using the site of AoPS for olympiad level problems

Can anybody pls suggest a good book for number theory for Rmo

- 2 years, 2 months ago

The most difficult problems of stage 3, along with stage 4 are eligible for RMO. However 300+ point problems wont be asked till INMO.

- 2 years, 8 months ago

Do you know books for geometry.

I have finished RD sharma class 9th and 10th.PLease a challenging problem solving book for geometry and source of how to get it.

Can anyone suggest me some basic books for rmo preparation ? I have finished syllabus of 9 and 10 with ncert

- 3 years, 7 months ago

yes!!! according to me ..RMO questions are of same as level 5 of Brilliant ...... so for that this is the best site to prepare for.. i guess.... or as we all know Mathematics is all about certainty...so i'm damn sure of that!!!

- 5 years ago

Is there any site similar to Brilliant? Online troubleshooting, etc. ... Even in disciplines other than mathematics.

- 5 years ago

I think level 4 is partially of RMO level, and level 5 of INMO level.

- 5 years ago

Prefer book of arihant publixation by rajiv manocha for rmo
Easily available at nearly rs 200 Best book for a rmo candidate Also follows syllabus i.e no diffrentiation or calculas

- 5 years ago

what about Challenge And Thrill Of Pre-College Mathematics by V Krishnamurthy, C R Pranesachar

which one is better ?????

- 5 years ago

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"??

- 5 years ago

but yes I can guarantee that there would be no other book except Rajeev Manocha, with a bucket of mistakes.....

- 5 years ago

That's absolutely true.....many things,mostly proofs have been left incomplete,some answers too are wrong.....
