That old note is very heavy now. We can use this note to communicate.

Note by Harsh Shrivastava

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.

,@Aniswar S K.What is yours score.

- 4 years ago

I am getting 248(P: 82 C: 83 M:87)

18 marks in maths were directly from cengage so i did it faster.

How much is Saarthak Behera getting??

Are u writing a mail for answer key changes??

- 4 years ago

If the keys are corrected I will get P-101,M-82,C-63.Total-246.

- 4 years ago

Is this according to this key or the corrected one......You will probably top if this is according to the incorrect key.I don't know sarthak s....He doesn't disclose his marks to anyone...So no one bothers his marks

- 4 years ago

All that we discussed here will change but I don't know abt chemistry.

And Nimay Gupta is getting 263.

- 4 years ago

As per incorrect key???Or correct one.

- 4 years ago

Crrct key.

- 4 years ago

Oh that's a great score.I asked some of my friends and sir as well they say in that chem question both 'A'and'B' are possible.So let's hope for best..

- 4 years ago

Incorrect one

By the way your physics score is amazing!! Do you take any measures to avoid silly mistakes??

- 4 years ago

I am not the right person to answer this...I myself make a lot like this time in chemistry...

- 4 years ago

Today at Fiitjee our sir told that answers may change, so by crrct and key I am getting P -79 C-61 M - 86.

Aniswar your chemistry score is awesome!!

- 4 years ago

What about that physics matrix will it change?And that q on C(2)H(5)0(18).

- 4 years ago

Ya his chem score is fabulous.Same with me if keys get corrected I will get-P-101,M-82,C-63.

- 4 years ago

Which ones are gonna change.....As your sir said.

- 4 years ago

@Aniswar S K No they haven't changed the answer keys.I enquired today.I got the same as I expected.abt 222.And fiitjee has a rigid system so no more hopes.Sarthak got abt 239.

- 4 years ago

Results out?

- 4 years ago

No I just asked them about the marks...May be they have deleted some q.And I checked the solutions provided by fiitjee.In the HCL/SN1 q they mention alcohol as the ans but give aldehyde

- 4 years ago

Where are the solutions and marks available?

- 4 years ago

I will be joining you all from November :)

- 4 years ago

Awesome!

- 4 years ago

@Harsh Shrivastava,@Aniswar S K .How much in today's aiits.How was it for you

- 3 years, 12 months ago

i am getting around 150 it was not a very quality paper. how much are you getting??

- 3 years, 12 months ago

Ya one of the worst.Ssly if they had to keep 2 subjects easy they must have set the other one really hard.I haven't checked the keys.Individual scores?

- 3 years, 12 months ago

51,57,42(CMP) I lost 12 marks in the physics match the following. I though that since energy is released heat must be negative

- 3 years, 12 months ago

Me 63,50,abt 37(PMC)Hey I know my chemistry is kinda bad.But tell me is the volume occupied by ideal gas 0??I didn't know that Biomolecules was going to be asked.And Physics I think I would get full as the answer to the assertion-reason q seems incorrect..

- 3 years, 12 months ago

Which assertion q's answer do you think is incorrect??

For that assertion question, are they asking Seebeck effect or like normal conductor??

Volume occupied by the molecules of an ideal gas is zero. That's why we put V-nb = V

- 3 years, 12 months ago

That $F=(i\int dl)×B$.It was correct I guess.Both assertion and reason with reason being the correct explanation......

- 3 years, 12 months ago

I think B must also be inside the integral

- 3 years, 12 months ago

But it is given that B is constant.

- 3 years, 12 months ago

That is only for statement 1

- 3 years, 12 months ago

Here even definate integration is not started , I left the two questions in first 6 in maths.

- 3 years, 12 months ago

I am getting around 170 , one answer in chemistry is wrong,(that sucrose in matrix)

Was this paper even of mains lvl?

- 3 years, 12 months ago

It was easy but who knows if jee can't set an easy paper to increase competition. See you were worried abt getting into top-100 but with that score I must say is enough for a rank of within-20.What's your individual scores and from your centre?

- 3 years, 12 months ago

Bro but iit ain't gonna set that easy paper anyways , P - 54 C - 64 M - 54.

Ppl from my center are also scoring between 160-180.

Ranks in this paper would not be beneficial I guess,because many bright ppl might have made some sillies.(happened in my center.)

- 3 years, 12 months ago

Your chemistry score is pretty high....that's good...Mine is just too low.

- 3 years, 12 months ago

You didn't knew that biomolecules were coming,I guess ,so don't worry!

- 3 years, 12 months ago

Hey really who is touching 180 ?? Nimay or suyash or both??

- 3 years, 11 months ago

Suyash did not gave the exam,Nimay getting 186.

Wbu?

- 3 years, 11 months ago

160 he bas

- 3 years, 11 months ago

In ours centre we have nt got good marks.Highest is probably (154).Most of us have screwed up chemistry......What's going on in your fiitjee?Our course is over and review classes have begun a week back.They have shrunk our CM batch(30) to a batch ofof(7+23).

- 3 years, 11 months ago

We have completed organic,qualitative analysis, liquid solution. In physics, electromagnetic induction over in maths, definite integration is going on.

Wow, your course completed very early!! BTW what happens review classes?

- 3 years, 11 months ago

Teachers give challenging questions to solve in class for some time and also discuss the doubts of the questions in the class itself.Also assignments are provided to be completed in home.And all the teachers concerned with all of 12th batches get chance to teach u.So u get the exposure from all good teachers.

- 3 years, 11 months ago

you got air 12 I guess Congrats!!

- 3 years, 11 months ago

Yeah just saw the result in evening. Thanks.

BTW this test was not of good level.

- 3 years, 11 months ago

Hey do you know anugyan Das.He joined our fiitjee probably coz I saw his name in our list.My friends told he hails from fiitjee bhilai.

- 3 years, 11 months ago

He used to live in Bhubaneswar but now he is in Bhilai with us.

- 3 years, 11 months ago

Aiits 2 results are out I got 61

- 3 years, 11 months ago

Hey guys have you seen the aiits-4 results.I got air-22 with 144 marks.Sarthak is air-5 this time.

- 3 years, 8 months ago

Yeah nice rank bro!

I got air 78 with 124 marks. From my center this time 9 ppl are under 100 rank. Wbu?

- 3 years, 8 months ago

Don't know.I checked only my result in fiitjee south Delhi website.

- 3 years, 8 months ago

i got 152 marks. Chennai people's marks r not there in fjee south delhi website. According to mark, i shud be 14 or 15th rank

- 3 years, 8 months ago

- 4 years ago

Oh that's good.How much did you get in P,C,M?Any suggestions towards keys?

- 4 years ago

C -61 M -72 P - 78

- 4 years ago

Wbu?

- 4 years ago

P-90,M-76,C-57.Hope that I would get (101,81,57) after correction

- 4 years ago

Can you post answer for that matching in physics? Energy one

- 4 years ago

I marked a-P,b-R,c-P,Q,T,d-Q.x<x2 isn't permissible always say if its less than x(1) the particle can't be found so its clearly incorrect.There is a q of Mutual Independence which I always find in Matrix ones.....Like if a,b,c are in a GP then they can be a AP as well(a=b=c)......This always leads to controversy

- 4 years ago

Even I have marked the same hope its correct.

Yeah, there shud be no ambiguity in any question, but even in IIT papers are some ambiguities :(

Don't you think abt that HI cleavge one?

- 4 years ago

Ya its correct I guess..First one you add 4HI to get 2I but due to large size and vanderwalls forces between iodine they would get eliminated to form a double Bond and next we can add another HI.But I think that Ether cleavage question ans should be both C(2)H(5)OH and the aldehyde.H20 is a better nucleophile than cl right....

- 4 years ago

Yup I know that 2 I next each other repel and have no objection to that answer.

My concern is what should we consider as major product the ring ones or the aliphatic?

- 4 years ago

Ya they haven't specified that.....I think the ring ones are major.

- 4 years ago

Why?

First the ring ones will have hydroxyl group after that only I would attack.

And SN2 on ethyl ones would be fast I guess.

What is your thought?

- 4 years ago

Ssly I didn't give that much thought. The q clearly says "they absorbed".So I thought only those ones.

- 4 years ago

Let's leave that question. You are correct I think.

- 4 years ago

Just one last question, top 100 cutoff shud be how much? Sry for lame question but my target was to be in top 100 I know I am very behind though.

- 4 years ago

May be around 226 for top 100.I was surfing through last years results.246 stood at air-41,226 at air-99.

- 4 years ago

Thanks a lot bro!

- 4 years ago

I made some calculation mistake my marks are ~ 205-207 :(

- 4 years ago

Ohk...The paper wasn't that easy. Esp Maths was nice.

- 4 years ago

Thanks but it was easy for you guyz :)

I willo work harder to get into top 100 in at least aiits.

- 4 years ago

You will get it this time.Your score is quite good.........I feel quite bad,I worked very hard for a good score in Chemistry....but shit.I failed again.

- 4 years ago

Thanks but I don't think I would be in top 100 anyways leave it I will try to be in top 100 in next one (only 4 weeks to go)

All the best! :D

- 4 years ago

Yeah answer shud be both though I chose the aldehyde.

- 4 years ago

Ya I too got that k must be negative and bro how did you know that f"(2x)=f(x)f'(x).Question says different.....as per q the f(x)=x^3/9.And HI cleavage I got 1 incorrect and rest 3 were right

- 4 years ago

I didn't got that maths question right.Aniswar told that.

And HI cleavage I got only 1 right.

- 4 years ago

That physics matrix 2 were incorrect. What's your opinion?

- 4 years ago

Acc to me matching Q1) => A-P B- R C-Pqt D - Q

U?

- 4 years ago

Same here...

- 4 years ago

f"(2x)=f(x)f'(x) they copied the question wrongly from cengage!!

Next probably they will go for arihant or balaji publications!!

- 4 years ago

Ya the prev one is bulky.So Harsh,Thanx........

- 4 years ago

You guys should make a slack team . communicating on brilliant is troublesome .I Must tell you that we guys gained a lot due to communication and intellectual discussions on doubts on slack .

- 4 years ago

Thnx for suggestion bro! Were aops discussions useful for your prep?

- 4 years ago

Somewhat. got to know many people and got some good questions which were posted as doubts

- 4 years ago

I have created a slack team If you would like to join pm me your email Id.

- 4 years ago

harshus99@gmail.com

- 4 years ago

Did u get an invite??

- 4 years ago

Yup got it.

- 4 years ago

Why is it troublesome?

- 4 years ago

Looks like you haven't tried slack yet. try slack

- 4 years ago

Do you know any students from fiitjee Delhi who would like to join??

- 4 years ago

Hy my slf Apoorv Saxena . Please Harsh can you send me an invitation of yur slack team?? My id is purnima.atul@gmail.com

- 4 years ago

@Aniswar S K,@Harsh Shrivastava The only answers that have changed are Chemistry ether cleavage question.The correct answer is given as C2H5O18.But they haven't given the first option as the answer.Maths-Only grace marks have been awarded in q on the polynomial function q,range of y=g(x)(I think that's correct),and answers in the matrix on graph last q hasn't been given as a grace.Physics-Only one the q on current in branch DE is zero. I checked in my fiitjee account.

- 4 years ago

Will they released results or not? Its more than 2 weeks now...

- 4 years ago

No I didn't find the results......Its been too late.BTW did you have phase test 4 this week.

- 4 years ago

@Spandan Senapati - yes we had

- 4 years ago

OK...

- 4 years ago

Did you guys receive the result.I received them over mail today.

- 4 years ago

What's your rank and marks? I didn't received any results.

- 4 years ago

What's your rank and mark?

- 4 years ago

I have not received results now. Tell your rank+marks bro.

- 4 years ago

Rank-82,Mark-226...I guess the 100 cutoff might be abt 220.

- 4 years ago

Hey are the questions where there is asterisk sign bonus marks awarded ? I mean are your marks consistent with the answer key provided by them on south Delhi website?

- 4 years ago

Ya not the matrix quetion in maths.I saw that I didn't get grace in that.Don't you have a fiitjee login account.You can see your checked omr there.

- 4 years ago

There is something hell wrong , my marks in maths and chemistry are according to to the key and I am getting as expectec in them but in physics, I am getting very less, I should have got 79 with the key but they are showing only 44 I don't know why :(

My total should have been 226 but as of this bullshit it is 191, I don't know why but they have damn sure made some mistake in checking my omr. I might have got an air of 76 but now it is 312 :(

- 4 years ago

Ya..May be I also think so.There might be some error.You create a fiitjee login account.You can see what your responses were....And what marks you've been awarded..But I also got less in maths..

- 4 years ago

How much difference bro?

I have got 35 marks less very disappointing , was expecting to be in top 100 for the first time but these careless ppl really piss me off :(

- 4 years ago

Not much as yours. Next aiits is just abt a week ahead.This one proved to be quite a bad one for me.Let's hope for the best in the upcoming one..

- 4 years ago

Something like this happened with me in class-11 aiits-4.I expected quite high score in Physics but it came down to low when I saw the results.

- 4 years ago

Many have got same ranks.My friend and me both with 226 have got 82 rank.

- 4 years ago

Oh I saw one of my frnd for 227 and rank is 76. My real marks are also 226 so we both might have got same rank(82).

- 4 years ago

How was aiits

- 3 years, 12 months ago

@Harsh Shrivastava how was this monthly test?

- 3 years, 11 months ago

Went veryy bad,made many mistakes, scoring only 130 :(

Wbu?

- 3 years, 11 months ago

Hey we too have a monthly test today......But I don't think our syllabi match.Coz we have got Qualitative analysis and the test is for the CM batches only.

- 3 years, 11 months ago

Yh the syllabus was different.

- 3 years, 11 months ago

Well, it was not good for me too. I made very silly errors in physics particularly that 2nd comprehension. Anyways securing abt 157. Who's highest scorer from bhilai?

- 3 years, 11 months ago

C Nikhil 203

- 3 years, 11 months ago

Whats the full marks?

- 3 years, 11 months ago

225

- 3 years, 11 months ago

Ours was 186.

- 3 years, 11 months ago

@Harsh Shrivastava @Spandan Senapati have you heard we will not be getting our aiits result held on 31st July

- 3 years, 11 months ago

Why.?

- 3 years, 11 months ago

How was aiits?? I am getting 200

- 3 years, 10 months ago

Your marks according to current answerkey?I believe some are wrong.

According to current anwer key = 182.

Our maths course not over (not even differential equation completed!) so could not do some in maths,and in chemistry,electrochemistry is left.

- 3 years, 10 months ago

Yah some things are wrong. I don't know how many changes they will make. Even for us vector 3d and probability not over

- 3 years, 10 months ago

That's,a good score with what you have studied.I think fiitjee should maintain a correct balance between the dates of aiits....So that it becomes a open competition.

- 3 years, 10 months ago

No , I commited a lot of bad errors in all subjects, anyways what's your score?

Our cousre might be over by November.

- 3 years, 10 months ago

Quite sad. Getting 216,as per this key. Although some answers are wrong. I might end up with around 240.But still its not up to the mark. Some answers I feel wrong are heating lead nitrate gives lead oxide, oxygen, nitrogen dioxide..So it's redox. And maths that value of k=1 coz I was getting the value as 21.And physics that inductor(L1 and L2) are wrong. And the matrix on energy, momentum conservation as well.

- 3 years, 10 months ago

Yeah those are wrong, but in that redox one,oxidation state of lead is not changed and they have asked about lead only. Also the k4fe(cn)6 one,fe+3 Shud not be the answer, it dissolves, even thought i marked pb+2 also. Also the organic matrix is not full correct I think, what do you all say?

- 3 years, 10 months ago

Hey they have asked about if the compound of lead undergoes redox.Not specifically about lead.Nitrogen and oxygen belong to compound and they do undergo redox right.And I also feel the answer to the phy matrix on direction of induced currents is wrong.I expected about 90+ in physics but as per key got only 72.

- 3 years, 10 months ago

In the physics matrix match How can energy of the system remain constant even when friction is there??

- 3 years, 10 months ago

A lot of answers in that matrix are wrong.

- 3 years, 10 months ago

In fact all.

- 3 years, 10 months ago

Have u received review booklets and gmps??

- 3 years, 10 months ago

We had received gmps in mid class 11.No Review booklets in chem and physics.Had got 1 advanced review booklet in physics and 1 for mains.Here its like if you have done the packages,CPPs,and your performance in tests is good(say within top 5 in centre)etc then you can go ask for a gmp right then.

- 3 years, 10 months ago

I think the organic matrix is a bit incorrect..Last one is a acid-base reaction(phenol+base) so I don't think its substitution reaction.

- 3 years, 10 months ago

Great score of both of you Aniswar and Spandan!!

- 3 years, 10 months ago

Slow and steady wins the race. In fiitjee kk nagar last year portions were over by February (2017) and the topper got air 40!!

- 3 years, 10 months ago

@Harsh Shrivastava Bhilai topper score? I'm getting about 180 according to current answer
key

- 3 years, 10 months ago

Anugyan Das - 220-230

- 3 years, 10 months ago

Hey,I got the revised keys in my account.The changed answers are Chem-Lead Nitrate Q.Its B,C both.Maths-None.Phy-The matrix on EMI,Inductor question.The matrix on Energy hasn't been changed. Got 226(C-71,M-75,P-83)

- 3 years, 10 months ago

You got your rank?

- 3 years, 10 months ago

- 3 years, 10 months ago

@Harsh Shrivastava @Spandan Senapati did u see aiits 3 ranks??

- 3 years, 10 months ago

Your marks, my marks is 188 acc to new key.

Congrats to both of you!

I might be 138.

- 3 years, 10 months ago

From where did you see results.Is it available online.

- 3 years, 10 months ago

Just search the fiitjee south delhi website.And i have not officially seen the result.

- 3 years, 10 months ago

Where is it available.Also how did you know mine.

- 3 years, 10 months ago

i think spandan senapati is 14. i am 24

- 3 years, 10 months ago

Yep,got 14th rank.

- 3 years, 10 months ago

hey guys finally i opened brilliant after a long time . how is life ?

- 3 years, 10 months ago

Hi, nice to see you again. Hows life at Khargapur?? Life's devoid of any excitement. Same mundane job daily. Do you have any suggestions to us at this stage??

- 3 years, 10 months ago

Yup aniswar pointed out right :P Did you also faced this situation?

- 3 years, 10 months ago

Hi.I also wanted to know the answer of his question......How was your midsem exams?

- 3 years, 10 months ago

Never ask an IITian about his exams :P . Jokes apart they were good . They were like our typical board exams . Currently i am at home for Durga Puja vacations (West Bengal you see). I Will go back on 2nd October and after that i will come to know how i faired in the midsem exams after knowing my marks :P. Regarding the monotonous schedule thing yeah that happens with everyone .When your syllabus gets over it seems a boring job to do those old things again .I Promise you work hard for 8 months more it will be rewarding. Life at IIT's will surpass your imagination and mark my words your Hardwork will be worth it . Just continue this zeal and I'm sure all of you will come out with flying colors. And if you are feeling tired and getting bored of monotonous schedule then take a day off. Rejoice yourself and motivate yourself to work hard from next day. All the best guys and if you have any problem just ping me on quora or fb . i will be happy to help you

- 3 years, 10 months ago

Life at KGP is awesome. the environment here is too good for learning, there are no motorised vehicles as such inside the campus so the campus is lush green , pollution free , away from the hustle bustle of a city and its huge! (2200 acres. KGP Is bigger than the area of IIT Delhi , Bombay and Kanpur combined). The Agricultural engineering department of IIT KGP Is bigger than full IIT Delhi and IIT Bombay :P .(around 400 acres). There are hell lot of opportunities here to explore your interests and pursue them apart from excelling in academics.

- 3 years, 10 months ago

How is today's Ai2ts

- 3 years, 9 months ago

Only 116, course is still not done,and forgot all class 11th radioactive stuffs :P

Wbu?

- 3 years, 9 months ago

We haven't received the keys. It was average for me.

- 3 years, 9 months ago

How much in PCM? Is the key incorrect

- 3 years, 9 months ago

56,30,66(PCM)

- 3 years, 9 months ago

i think 3 ans in chem are wrong and 1 in physics, the graph with dn/dt

- 3 years, 9 months ago

I got PCM(51,25,67)as per this key.And yes physics it must be A,D.Also in chem that coordination q,Electrochem q are wrong.

- 3 years, 9 months ago

They copied all the Multi type, integers from package...... Stupid people.

- 3 years, 9 months ago

Im getting 130 with the current key. What's Nimay's score?

- 3 years, 9 months ago

How is aiits 5? How much you all are getting?

- 3 years, 8 months ago

How much in NSEP?

- 3 years, 8 months ago

Hey not given NSEP .and infact not given any of the olympiads

- 3 years, 7 months ago

@Aniket Sanghi,@Prakhar Bindal how are the full test papers 1 and 2, i.e, the aits papers that are uploaded on the web for practice??

- 3 years, 7 months ago
