JEE 2015 approaching!

As around just 100 days left in JEE Advanced 2015, I have decided to post a set of 8 problems every week (4 topics/set, 2 questions/topic). I hope these sets will cover most of the syllabus. $\ddot\smile$

Solutions will be added, if not already posted, after a week.

I'll keep on updating this note to add new links every week. Feedbacks and suggestions are welcomed.

So here goes my list:

My Picks for JEE 1
My Picks for JEE 2
$(i)$ My Picks for JEE Advanced 1 $(ii)$ My Picks for JEE Mains 1
$(i)$ My Picks for JEE Advanced 2

Easy Math Editor

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Best Of Luck To Everyone !!!

It would be nice if I could get into a good IIT and it would be even better if someone from Brilliant is there with me .

A Former Brilliant Member - 6 years, 4 months ago

Best of luck to you too! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

Aren't all IITs good?

All the best

Ritu Roy - 6 years, 4 months ago

Yes, I think 'good' is a relative term. They are better than other colleges in India. But IIT-B is better than IIT-Bhu or IIT-Roorkee. So we can't say IIT-Bhu is bad. That's just a comparison.

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Yeah, actually I was indeed referring to IIT-B, getting to study CS at IIT-B would be the best !!!

A Former Brilliant Member - 6 years, 4 months ago

@Pranjal Jain – How's IIT Madras?

Ritu Roy - 6 years, 3 months ago

@Ritu Roy – Its on number 4 in my list. After Bombay, Delhi and Kanpur.

Pranjal Jain - 6 years, 3 months ago

Here's the next Advanced one. Mains will be coming tomorrow. Any suggestion/idea?

I'll also welcome chapter requests as in which chapters do you want. I get confused like "Should I post this one or that one? This is interesting but that's important..." and then end up posting bad or not-so-good questions.

Pranjal Jain - 6 years, 3 months ago

Your questions are great.. if not the best. I don't think you should call them bad.

Which coaching centre do you go to?

Ritu Roy - 6 years, 3 months ago

Resonance

Pranjal Jain - 6 years, 3 months ago

@Pranjal Jain Can you please post Chemistry questions?

Anuj Shikarkhane - 6 years, 4 months ago

Well, I can post physical chemistry problems but then for organic and inorganic chemistry, problems will be disputed too much. I'll try to post physical chemistry problems! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

Ok..No problem

Anuj Shikarkhane - 6 years, 4 months ago

I don't think there is much scope to debate on problems on inorganic chemistry although I have to agree that questions on organic chemistry may cause a debate. But I would still encourage you to put up questions on these topics because that would at least provide a platform to discuss chemistry related topics on brilliant.

Sudeep Salgia - 6 years, 4 months ago

@Sudeep Salgia – Thanks for suggestion! I'll try. But as you can see $\left \lfloor \dfrac{109}{7} \right \rfloor=15$ sets can be posted at max. (Can't post more than one/week as time don't allow me) $15×8=120$ problems will be posted. Now dividing them among chapters, I don't think I'll get more than 2/chapter.

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Don't worry a lot of people on Brilliant will help you. At least I would. I would once again begin posting problems once my mid semester exams get over and I get some time to think and post problems and that is by the end of February.

Sudeep Salgia - 6 years, 4 months ago

@Sudeep Salgia – Oh! So nice of you! Thanks!

Pranjal Jain - 6 years, 4 months ago

Hi @Pranjal Jain , here I have posted a Physical Chemistry Question . I'd like it if you included it in your set.

It's just a suggestion !!

A Former Brilliant Member - 6 years, 4 months ago

@A Former Brilliant Member – I'll surely try to include it in relevant topic! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Thanks

A Former Brilliant Member - 6 years, 4 months ago

Second set launched!!

Pranjal Jain - 6 years, 4 months ago

nice set of questions... but i guess you should increase its difficulty as it would be more challenging and interesting...

Harshvardhan Mehta - 6 years, 4 months ago

Sure! I'll keep it in mind next time. I think its difficulty level will increase gradually. 😏

Pranjal Jain - 6 years, 4 months ago

Any feedback on new set?

Pranjal Jain - 6 years, 3 months ago

Good Practice of Conics for JEE: Conic Challenges for JEE

Ninad Akolekar - 6 years, 4 months ago

@Pranjal Jain

Haha , 100 day streak ! Congrats :)

A Former Brilliant Member - 6 years, 3 months ago

Anyone uses Physics Galaxy by Ashish Arora as a reference book for physics??

Ninad Akolekar - 6 years, 3 months ago

Yes, I do! But only for Mechanics.

Pranjal Jain - 6 years, 3 months ago

What references do you use for other topics of physics, please tell me.

Ninad Akolekar - 6 years, 3 months ago

@Ninad Akolekar – For EM, I prefer Anurag Mishra. For Waves/Optics, I don't use any specific book. I use MCQ by Deb Mukherjee in general.

Pranjal Jain - 6 years, 3 months ago

@Pranjal Jain – Thanks!!

Would you tell me good reference books for other subjects as well? (only if I am not disturbing you much; I know you are busy with your JEE prep) .I have just completed my class 11th course in my coaching.

Ninad Akolekar - 6 years, 3 months ago

@Ninad Akolekar – For maths, I use "TMH for JEE Advanced"

For Organic Chemistry, "MS Chauhan"

For Physical Chemistry, I use book written by my teacher, SM Sir (Disha Publications).

Pranjal Jain - 6 years, 3 months ago

Your sets will now be useful for future aspirants like me! ( Though I don't want to be an Engineer, but a mathematical physicist).

Swapnil Das - 5 years, 10 months ago

Good Work Bro.. and good questions too.. keep it up,,

Harshvardhan Mehta - 6 years, 4 months ago

Thanks! I think it would be better if I include problems by other members also. @Sandeep Bhardwaj has some nice sets for JEE. And he won't mind me stealing one or two questions! Though I think new problems would be better. Whats say?

Pranjal Jain - 6 years, 4 months ago

Yeah thats a good idea... also check out problems for mechanics and electricity magnetism

Harshvardhan Mehta - 6 years, 4 months ago

@Harshvardhan Mehta – Yeah! Sure!

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Check out my question ''JEE mechanics problem 1'' I have contributed it to your set

@Pranjal Jain and @Harshvardhan Mehta

Parth Lohomi - 6 years, 4 months ago

@Parth Lohomi – Well, Can you explain if you want us to find distance travelled after removing the 5 kg block or since the start? And are we supposed to calculate the height or the distance travelled?

Pranjal Jain - 6 years, 4 months ago

Best of luck!!

Parth Lohomi - 6 years, 4 months ago

Good ahead dude ! I always support innovative and useful stuffs. Keep it up !

Sandeep Bhardwaj - 6 years, 4 months ago

@Sandeep Bhardwaj – Is it "Good+Go ahead"? Lol! Thanks! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Yeah...it's the same. You got it right.

Sandeep Bhardwaj - 6 years, 4 months ago

nice work man!!

yashasvi baweja - 6 years, 4 months ago

Thanks! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

keep up the effort!

Ishita Bhatia - 6 years, 4 months ago

Thanks! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

Good effort. Keep posting

And best of luck for JEE.

Ninad Akolekar - 6 years, 4 months ago

Thanks! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

Nice work ! Hey Please Post Mechanics and E+M question also , Thanks !

Hey Also share Your Views on this Note If you don;t mind :: JEE Coming

Karan Shekhawat - 6 years, 4 months ago

I'll surely share my views! I think Mechanics and EM may appear in next set! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

This is a great initiative that you have got going , thumbs up !!!

A Former Brilliant Member - 6 years, 4 months ago

Thanks Azhaghu!

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain

Great! Thumbs Up to your idea!! This is definitely an inspiration motivation to all IIT aspirants out there.

All the Best for your examinations.

Ritu Roy - 6 years, 4 months ago

Thanks! I recently found there are so many JEE aspirants here.

Pranjal Jain - 6 years, 4 months ago

Include me in your ''aspirants'' list! @Pranjal Jain

Ritu Roy - 6 years, 4 months ago

@Ritu Roy – Included! You'll be contesting as NRI? (From Bahrain?)

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Nope. I'm in grade 10 now.

Ritu Roy - 6 years, 3 months ago

Hello guys...

Inspired from Pranjal's message board i have also created something similar... pls check it out

JEE at door Steps..!!!

Harshvardhan Mehta - 6 years, 4 months ago

This is not my 'message-board'... Lol. I noticed you are really inspired by me! Copied the concept and even my lines!! 'So here goes my list' -_- Well, I won't really mind it. 😜

Pranjal Jain - 6 years, 4 months ago

m sry bro u see m bad at forming those... alright i'll change them

Harshvardhan Mehta - 6 years, 4 months ago

@Harshvardhan Mehta – Hey! Cmon! I was joking with you! I added 'I won't mind'. Never mind. Its totally fine!

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – ohhh.... wel how are your prep for jee nd whats your expected score?? and which branch you wanna pursue?/

Harshvardhan Mehta - 6 years, 4 months ago

@Harshvardhan Mehta – Well, I posted this on a note JEE coming... by Karan Shekhawat. Can you check it out there? What I didn't posted there is the branch. I love computer science (though I am Level 3 here, don't know anything about python). Even I have Computer Science as 5th subject. So that's gonna be CS most probably. I would be happy if I'll get it in IIT-B or IIT-D or IIT-K.

Pranjal Jain - 6 years, 4 months ago

Nice problems! Best of luck to everyone!

Pratik Shastri - 6 years, 4 months ago

Thanks!

Pranjal Jain - 6 years, 4 months ago

Can you post some problems for combinatorics...????? Plz!!!

Mohit Khanwale - 6 years, 4 months ago

This set contains two nice probability questions. You may also see some combinatorics questions on my profile. Sorry but I don't think combinatorics will be in set 2. It might be back later.

Pranjal Jain - 6 years, 4 months ago

OK thanks....best luck for jee.!!

Mohit Khanwale - 6 years, 4 months ago

@Mohit Khanwale – Here are some problems on probability for JEE-Advanced. All are nice ones and relevant for JEE. Thanks to @megh choksi

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Thanks a lot!!!!😁

Mohit Khanwale - 6 years, 4 months ago

Y dont you try these, Combinatorics and Probability set by @Andrei Golovanov it consists of the most interesting and challenging question till date and second my set Combinatorics Challanger.

Harshvardhan Mehta - 6 years, 4 months ago

So I have added solutions to problems without a nice solution or if I had alternate solution. Gonna post next set tomorrow morning. (IST) Cheers! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

Given the fact that some problems in these sets are really easy, I am thinking of posting two sets per week, one for Mains and other for Advanced.

As @Harshvardhan Mehta pointed out, questions must be challenging. But at the same time, JEE Mains should also be taken cared of. So I hope this is a better idea.

Any comments/suggestions?

Pranjal Jain - 6 years, 4 months ago

Nice idea!

Pratik Shastri - 6 years, 4 months ago

Electrostatics is one topic that has been left out , can you post some questions on it ?

A Former Brilliant Member - 6 years, 4 months ago

Very soon! Maybe in next one! $\ddot\smile$

Pranjal Jain - 6 years, 4 months ago

thanks for taking my review into consideration..

Harshvardhan Mehta - 6 years, 4 months ago

I was actually a bit busy with my board practicals, so couldn't get nice questions. I realised this very soon. Working up on next set(s)

Pranjal Jain - 6 years, 4 months ago

@Pranjal Jain – Yep that always comes first.. Looking forward for your next set of qestions.. :) and yeah a request can you try and give e a feedback and level suggesion on my set of questions.. you already know the note so....

Harshvardhan Mehta - 6 years, 4 months ago

New sets launched!! I hope you guys will enjoy them. Keep posting solutions and resharing problems. $\ddot\smile$

(3 chapters, 6 problems)/set this time as I focussed on quality more than quantity. Actually quantity has increased as 2 sets are there this time. Anyways, cheers!

Pranjal Jain - 6 years, 3 months ago

I am confused with which chapters should I post in next set. Any idea/suggestion?

Pranjal Jain - 6 years, 3 months ago

You can try Ionic Equilibrium, Qualitative Analysis, Coordination compounds, Electrochemistry

Rajorshi Chaudhuri - 6 years, 3 months ago

So much Chemistry? -_- Ok I'll add Thermodynamics.

Pranjal Jain - 6 years, 3 months ago

@Pranjal Jain – Thanks for considering my suggestions $\ddot\smile$

Rajorshi Chaudhuri - 6 years, 3 months ago

@Deepanshu Gupta , @Ronak Agarwal ,@Pranjal Jain from which books (apart from coaching modules) have you been practising Physics for JEE , NSEP, KVPY and other olympiads ???

Shubhendra Singh - 6 years, 3 months ago

If you want conceptual but limited questionsquestions, see MCQ by Deb Mukherjee. Flipkart link, if you want questions ranging from formula substitution to some better ones, see Concepts of Physics by HC Verma. Flipkart Link for Part 1, Flipkart Link for Part 2 and finally, if you want problems on blending physics with calculus, there is a book by IE Irodov Flipkart Link

Pranjal Jain - 6 years, 3 months ago

Thank you very much.

Shubhendra Singh - 6 years, 3 months ago

Can somebody solve this Problem

manish bhargao - 6 years, 3 months ago

Hello everyone! I think I won't be able to post complete sets now, unfortunately! It'd be better if I post questions one by one whenever I find something interesting. Thanks for support! $\ddot\smile$

Pranjal Jain - 6 years, 3 months ago

Loved your questions ! Thanks for posting them :)

A Former Brilliant Member - 6 years, 3 months ago

All the best for your boards as well as your jee.

And, is electronic and communication not available in IITs? I checked a few sites but didnt find the category.

Can you name a few engg colleges in india apart from iits which are of equally high standards?

Thanx in advance

Ritu Roy - 6 years, 3 months ago

Thanks @Ritu Roy They are available. IIT-Kharagpur, IIT-Roorkee

BITS, Pilani is the only comparable college in India.

Pranjal Jain - 6 years, 3 months ago
