I'm in Class 10 and preparing for IOQM soo I'm looking for resources that are more challenging than the usual beginner stuff

What books, websites, YouTube channels, or problem sets helped you the most? I would love to hear what worked for you personally

Also if there's any book that's best for Olympiad problem-solving, please let me know. I'm ready to put in the work

Like we have books for IOQM: PJ Sir Pathfinder Junior book, VOS Book, Disha Book, PW Book

And for RMO-INMO: PJ Sir New Book (Similar to Pathfinder Senior) and Disha Book

So, what are similar books for the NSE stage and then further INO stage?

Like for Physics there's this new book by Anurag Mishra sir, which seems for NSEP, and we have the Physics Pathfinder for INPhO... Maybe that's for Physics.

But what about Chemistry, Biology, and Astronomy?

(I am only thinking about giving NSEP and NSEC, but asking about NSEB and NSEA too for other people)

We had books published by Arihant for Mathematics, Physics, Chemistry, and Biology till 2021, but they stopped publishing those after that.

I am a below avg math student (35.7% in 9th compartment). pls suggest how to be GOD at mats so I can get 100% in my premids on monday
syllabus:

1. Real numbers
2. polynomials
3. linear eqns
4. areas related to Circles
5. surface areas and volumes
6. statistics

Problem:

A fire burns at the top of a tower on the surface of the Earth. The Earth is assumed to be a perfect sphere of radius R. An observer stands on the Earth's surface at a ground distance d from the base of the tower. It is nighttime, the sky is perfectly clear, and atmospheric effects such as refraction, scattering, and absorption are neglected.

Assume that light propagates in straight lines and obeys the inverse-square law. Let I(min) be the minimum light intensity detectable by the observer's eye.

Determine:

1. The minimum height h of the tower such that the fire is just visible to the observer, taking the Earth's curvature into account.

2. The minimum luminous intensity (power) L of the fire required for the observer to detect it from the distance d, assuming the received light intensity at the observer must be at least I(min).

Express your answers in terms of R, d, and I(min), stating any additional assumptions you make.

10th grader here, learnt about nsec only this month.
since i barely have 5 months left for the exam,
what chapters should i do so atleast i have a shot at clearing the cutoff
so far ive only causally done some physical chem chapters.
[from delhi btw]

hey everyone and i am a 9th grader
abhi tk maine amc 8 complete syllabus, pura taiyar kr liya h
david burton's number theory bhi complete hai and number theory ke pyq bhi lg ja rhe hai
class 9 10 ke sare geometry concept ko proof bhi kr liya hai and acche se master kr liya hai
i want to know if it is enough!, because i am suffering from a disease and i am pretty sure it wont be cured anytime soon so mai abse leke 6 september barely 1 hour nikal paunga per day tak mai health or ioqm dono ka dhyan rkh pau
lekin agar ye enough nhi hai 30 marks ke liye to mai disease ke against jake 4 hours tk ki koshish krunga
please consider the fact that due to my illness i cant enjoy maths like i used to

Most students discover Olympiad mathematics only when they begin preparing for an exam. By then, they are often trying to learn advanced techniques without having developed the mathematical intuition and problem-solving mindset that top performers build over years.

We are launching a small and highly focused Olympiad Mathematics Foundation Program for students in Classes 6–10 who want to develop strong mathematical foundations and prepare for examinations such as:

• IOQM (India)
• AMC 8
• AMC 10
• AIME
• Other first-stage mathematics olympiads and talent examinations worldwide

The goal is not merely to prepare students for a particular examination, but to build the mathematical maturity required for long-term success in competitive mathematics.

About the Mentors

Both mentors have backgrounds including:

• Qualification in the CMI Entrance Examination
• Qualification in the ISI Entrance Examination
• Qualification in JEE Main & JEE Advanced
• Olympiad mathematics experience up to RMO/INMO/USAMO - level problem solving
• Authoring an Olympiad mathematics book
• Leading a mathematics organization that collaborated with mathematically gifted students(including IMO, USAMO, IMOTC peers) and communities from multiple countries
• Organizing and conducting Olympiad and mainstream mathematics contests
• Teaching and mentoring experience

Who Can Join?

Anyone from Classes 6–10.

No Olympiad background is required.

No advanced mathematical knowledge is required.

Even if you are completely new to Olympiad mathematics, you are welcome.

We will start from the fundamentals and systematically build toward advanced problem-solving and contest mathematics.

What Will Be Taught?

The program begins with foundation building and gradually progresses toward Olympiad-level thinking.

Topics include:

• Mathematical Thinking & Problem Solving
• Number Theory
• Algebra
• Geometry
• Combinatorics
• Logical Reasoning
• Proof Techniques
• Contest Problem-Solving Strategies

Students will learn how to approach unfamiliar problems, discover patterns, write rigorous arguments, and develop mathematical creativity.

Mode of Instruction

All classes will be conducted online, in English.

Batch Size

We are starting with only one batch.

To ensure meaningful interaction and individual attention, we will accept at most 10 students in this inaugural cohort.

This is intended to be a mentorship-oriented program rather than a large coaching class.

Fee

For Indians: ₹1000/hour 
Roughly Rs. 13,000 per month.

For Non Indians: $15/hour

Contact

Interested students and parents may contact us at:

Please mention:

• Student's class
• Mathematical background (if any)
• Olympiad experience (if any)
• Goals and interests

If you are genuinely curious about mathematics and willing to challenge yourself, we would be delighted to work with you.

I think its good level like conceptual is not that hard, its more math heavy.

Solution is here: Solution

S0 like guyz during summer i had bought pj sir ioqm maths book and i am like currently studying it but i feel like its too difficult and like it takes me a lot of time to understand it and i also studied from vos ioqm playlist which i find really intresting and i am able to solve and understand the problems so like i dont understand what to do now should i continue with vos playl ists and is buying the vos book worth it right now and i like studied basically nothing during summer so someone pls helpppp.
