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.

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

@Harsh Shrivastava
–
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..

@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.

@Harsh Shrivastava
–
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

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?

@Aniswar S K
–
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..

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?

@Harsh Shrivastava
–
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).

@Spandan Senapati
–
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?

@Harsh Shrivastava
–
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.

@Harsh Shrivastava
–
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.

@Harsh Shrivastava
–
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

@Harsh Shrivastava
–
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....

@Spandan Senapati
–
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.

@Harsh Shrivastava
–
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.

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

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 .

@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.

@Spandan Senapati
–
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?

@Harsh Shrivastava
–
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.

@Spandan Senapati
–
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 :(

@Harsh Shrivastava
–
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..

@Harsh Shrivastava
–
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..

@Harsh Shrivastava
–
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.

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.

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?

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.

@Harsh Shrivastava
–
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.

@Spandan Senapati
–
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?

@Harsh Shrivastava
–
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.

@Aniswar S K
–
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.

@Harsh Shrivastava
–
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.

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)

@Harsh Shrivastava

No,in fiitjee login you get to see your marked answers,correct answers and marks awarded.You don't have an account?Then sign in.Its helpful

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??

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

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.

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

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

Log in to reply

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

Was this paper even of mains lvl?

Log in to reply

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?

Log in to reply

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.)

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

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.

Log in to reply

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