Respected **Sirs** and **Dear Brilliantians**,

I do write this note on behalf of my friend Rajdeep Dhingra, and this note is an extension to one of his notes where he asked to provide some advice about NSEJS and other Science Olympiads.

Firstly, Please suggest some resources and Worksheets on Brilliant which would improve our Problem solving Strategies and olympiad skills in **Physics**, also please mention the Prerequisite knowledge.

Please do the same for **Chemistry** and **Biology**, by providing some questions and worksheets on Brilliant.

**Mathematics**:

Please suggest some prerequisite knowledge and kindly create some *Worksheets*(according to levels, so that we can progress gradually) which would increase our Problem solving strategies and Help us learn more.

We would be extremely indebted if some kind help is provided.

**Thanks**,

*Swapnil Das*

*Rajdeep Dhingra*

TopNewestPhysics is often confused with difficult mathematics, (you may also check mostly level 5 problems on brilliant.org) but according to me physics is a different branch of science which is needed to be understood in its purest form (The concept). Problem solving may involve mathematics. For understanding physics and concepts you need to be a great thinker and have strong imagination. Physicists and in fact scientist are often referred as philosophers as well.

I am creating conceptual problems on physics and posting slowly and steadily as and when possible (So keep following me :P ), Meanwhile you may refer to many books available in the market on these exams and start learning and preparing.!! Previous years exam papers will also help you understand the level and course coverage as well!!

Please see the QP and make a set or it. Also there are no books in the market or this. Please suggest some(for problem Solving). I would be thankful if U could make a set ASAP.

As i have searched on net

\(\text{Recommended Books for NSEJS:}\)

NCERT books of Phy, Chemistry, Maths and Biology (IX and X and selective topics of class XI)

Concept of Physics - HC Verma

Higher Algebra - Hall and Knight

Elementary Mathematics - Dorofeev , Potapov and Rozov

NSEJS is not that difficult, i cleared it last year mainly because of math, you will definitely get full or close to full marks in Math. So the topics of concern are PCB , I used mainly my coaching sheets for that , but if your coaching doesnt provide that you should do 11th and 12th class ncert for these subjects that will be more than enough. Also try solving previous year questions. I believe you can clear nsejs very easily, the problem is 2nd stage i.e. INJSO. It involves subjective questions which are of high difficulty level. Just for information , if u clear nsejs you will be eligible for INAO(Junior Astronomy Olympiad), you can clear that too if you are good at physics and Math. Just do 11-12NCERT. I Hope you will qualify the first stage easily. PS - I couldn't clear INJSO. And last year's cutoff was a little above 100out of 240marks in NSEJS.Math is only asked in first stage and not in other stages.

The JSO is the most broad spectrum olympiad as you have to be good at all 4 :PCMB You just cant do 11th and 12th syllabus fully, its very difficult , I couldnt and I didnt. One may say, Kushagra Juneja (Gold medalist ) did it and thus its advisable, but what I'll tell you is first make your basics of 9th and 10th grounded very well. Do AS MUCH of advanced chem as possible. Rest , the path will be clear!

Hey, red come to my mboard pls

Log in to reply

I am too a 9th grader. Which books should I use for Physics ,Chemistry ?and if possible then please tell about biology also.

Log in to reply

I will hardly recommend u hc Verma physics. Prepare from it. It is really a good book.

Log in to reply

Sorry @Rajdeep Dhingra and @Swapnil Das for late response. I am not a biology master and I don't know who tell you such peculiar things.

I would try to help you. For Biology first you must clear the basics. For that learn from NCERT class 9/10/11.Most important chapters are Cell , Diversity , Tissues , Life processes.

There are many books that are especially for NSEJS (I don't know which is the best so I won't recommend ) Solve them.And remember to solve as many previous year paper you can.

You will be able to manage physics , Maths and chemistry quite well.

And try to help me in Mathematics Olympiads. @Krishna Ar , @Ritwik Jain Help us (especially in bio)

Please tell some of those "Many books" for NSEJS.

Between I dont think the level of exam will be that difficult that you will need to solve Irodov. Try to cover maximum course rather then covering one portion from many books.

I believe at your level HC Verma should suffice any competition, If you are thorough with it..!!

No problem ! BTW Could U post some problems from that ? (Phys,Chem,Bio,Maths)

Log in to reply

Hi! This year I gave NSEJS and am expecting close to 190 marks in it. I am from MP and my coaching teachers have assured me that I will get selected for INJSO. But the problem is, I have exceeded the age limit. I spoke to my teachers regarding this and they told me that I will be allowed to write INJSO but will not be allowed to attend the OCSC. They told me that I will be taken up for Astronomy olympiad. Does this really happen? If yes, then how to prepare for astronomy?

Log in to reply

You will give INAO jr , but even if you clear it you won't be allowed to attend 3rd stage for it so no use of giving.
