I mailed Deepanshu Bhaiya about why he left brilliant.I am relieved now .He replied!: "I was Feeling lot's lot's of negativity .. But I hope everything will be fine soon .. It may take 1-2 day's .. but I will and I have to ... !
I messed up my OMR and huge number of silly mistakes in mains... I was not able to cope up with Exam pressure and collapse ... So I deleted Brilliant and now my primary focus is only JEE and JEE and JEE and I have no options since this is my last year ... Hope I will soon overcome with all negative thought's .. and I believe that " I will back soon " . "

I believe he will rock advanced.All the best Deepanshu bhaiya and all others.

Could you give me his Email

- 3 years, 9 months ago

Give me yours i will mail you.Coz if i post it here he will recieve lots of mail of people askink him about why?what? etc. Thanks

- 3 years, 9 months ago

I think ""pp " is not there in your id,is it?

- 3 years, 9 months ago

I don't see pp

- 3 years, 9 months ago

HaHa you modified it.Anyway i mailed it to you.

- 3 years, 9 months ago

In order to attempt JEE advanced, he must be 1 among the top 1,50,000 students, which is pretty good. So I dont think he should be filled with negativity.

- 3 years, 9 months ago

By the way, does jee mains score count for final rankings?

- 3 years, 9 months ago

- 3 years, 9 months ago

Thanks $$\ddot\smile$$

Error to be corrected in VMC answer key.

The answer to the question : A signal of 5kHz frequency is amplitude modulated on a carrier wave of frequency 2MHz. The frequencies of the resultant signal is/are :

Answer should be 2005,2000,1995 kHz and not 2005,1995 kHz.

Refer NCERT.

- 3 years, 9 months ago

You are right because the periodic function of the output tension can be written in terms of three cosine functions such That the frequencies are: 2000khz-500khz, 2000khz and 2000khz+500khz which Is the answer.

- 3 years, 9 months ago

Is 3 hours sufficient to complete the paper.

- 3 years, 9 months ago

Hey I got $$290$$ marks. Chemistry $$100.$$ Maths $$98.$$ Physics $$92.$$ I should have got better marks.

- 3 years, 9 months ago

- 3 years, 9 months ago

Yeah!!

But how did you recognized it??

- 3 years, 9 months ago

first of all how much is Ankur bhaiya scoring???...and i am currently in pinnacle ...(class XI)

- 3 years, 9 months ago

He's getting 301.

- 3 years, 9 months ago

paper was indeed easy, I did not leave any physics problem, though i did leave two maths problems (the boxes problem where he said boxes were indistinguishable but options were of distinguishable and the locus of image ) and two chem problems (the one where which salt is not yellow was asked, and the one where the polymer used for paint was asked)

hope fully i have not done too many silly mistakes, i shall be more precise only after Fiitjee relases its answer key

- 3 years, 9 months ago

Yes, even I got confused in box problem. Lets see what happens...

- 3 years, 9 months ago

@Pranjal you still didn't tell your marks yet ? Please tell bro.. I'am curious ..! And Congo. @Ronak Agarwal @Shashwat Shukla @Mvs Saketh .. you all guys rock it ! .... I'am nowhere close to you guys ... I get 241 marks ... Physics put me down ! But anyway's happy for u guy's :)

Wait But ... where is @Deepanshu gupta ..... ? :O ... I see he is deleted his account ... is everything is alright with him ? I don't know but i have bad feeling for him ... do you guys know anything about him ?
It will be bad if something bad happened to him ... I know if so .. he may be feeling afraid ,,, since as this is his last year ... Also does his problem is also deleted ... ??

- 3 years, 9 months ago

This is just the promo, the real thing is advanced bro, nothing is decided yet :)

yes, like i said, i hope hes fine, perhaps hard core prepping for jee advanced, or in a minor bout of fear which he will soon overcome hopefully

- 3 years, 9 months ago

Well, the promo sure doesn't seem to be that of a block-buster on this end.

It's going to be a long month ahead...

- 3 years, 9 months ago

yes it is, a long month, we have to work every skill we got, cause the slightest of errors or negligence and some one will push us back in the rank,,,, the real shit is coming, its exciting actually

- 3 years, 9 months ago

Out of the frying pan, into the fire.... let's dance!

- 3 years, 9 months ago

If only the chickens we cook in said pans shared your enthusiasm :D

- 3 years, 9 months ago

I would use the word exhilarating instead of exciting (because the former may or may not be pleasant), but yeah, this is the final lap of this two year long bloody marathon(I do feel rather strongly about the whole cut-throat competition thing).

Newton's ghost guide us all.

- 3 years, 9 months ago

two year long for you guys perhaps, i wasted my first year in meaningless activities , but yes still a marathon, just give everything i got to jee advanced and then i will never read a thing except physics and math all day all night! i am sure you have similar plans

- 3 years, 9 months ago

Spot on! That is the only thing I've wanted to do for a loooong time now. The pain of learning what colour bloody sulphides and carbonates and precipitates and what not, is sometimes just too much -_- (the sad part being they do ask such questions even in the advanced paper)

And you wasted your first year? By wasted I think you mean you became a total badass at physics and learnt advanced concepts and cleared Inpho in the process! :D

- 3 years, 9 months ago

indeed they do, there are a lot of (to be remembered stuff) in advanced as well, which many dont realise,

no, i wish what you said was true, but i did waste it , it was the summer holidays of 2014 when i realised could barely solve a few problems of jee advanced 2013 when i realised i have to run, and run fast and keep running faster, fortunately i could atleast partially catch up, and managed to crack inpho as well (you see i was interested in science back then as well, which probably helped me catch up, but i lacked the skill as i underestimated the vastness of knowledge and over estimated myself)

- 3 years, 9 months ago

You would make for a good public speaker, I think :D

I'll take your word for it all. But either ways, no point in worrying about split milk when there's the biggest 'jug' just $$waiting$$ to be split, huh?

Well, anyways, good luck with it all, and a good night to you :)

- 3 years, 9 months ago

indeed, best of luck :)

- 3 years, 9 months ago

He is feeling very low right now, he made mistakes in filling omr and in solving, it will take few days for him to recover but I am sure he will be back with a bang in advanced. He said he will be back soon :D

- 3 years, 9 months ago

- 3 years, 9 months ago

- 3 years, 9 months ago

Maths section is quite easy. Its of lower level than expected. !!!

- 3 years, 9 months ago

Yes, it was. But I didn't expected it to be tougher than this.

- 3 years, 9 months ago

- 3 years, 9 months ago

Thanks. Can you provide answer keys for other codes, if they are uploaded?

- 3 years, 9 months ago

@Azhaghu Roopesh M ,@Deepanshu Gupta ,@Pratik Shastri @Shashwat Shukla and all others who have not commented pls tell us about your experience of Jee main

- 3 years, 9 months ago

Hello I starting my jee prep from now l...coz I gave the 10th boards now.....so I want some tips from Ronak Agrawal,prangal Jain sir....please I want to get a top 100 rank In jee please give a reply....i have joined iitianspace classes

- 3 years, 9 months ago

You have joined iitanspace. That's great. Do you know Tyagi sir. I am a big fan of him.

- 3 years, 9 months ago

Where is @Azhaghu Roopesh M ?Where is he? He has been one of the most active person on brilliant.Pls reply bhaiya.

Edit: I got a mail from him also And he looks good but he didn't mention how main was.

- 3 years, 9 months ago

He will be inactive for a year. He says his Mains went well.

- 3 years, 9 months ago

Why for a year?

- 3 years, 9 months ago

Haha! Don't worry! He'll be back. We talked today for a while. He said he has to build up his physics from the basics till JEE Advanced.

- 3 years, 9 months ago

I expected this note to be filled with @Azhaghu Roopesh M 's comments. Surprised!!!

- 3 years, 9 months ago

@Pranjal Jain ; when he will be back ? after advance or after few days, please reply..

- 3 years, 9 months ago

For a YEAR???? Why??

- 3 years, 9 months ago

Did you take the exam?If yes,then how could you posted this note?

- 3 years, 9 months ago

Every 17 and some 18 year old Indian student have given JEE.... @Adarsh Kumar @Swapnil Das So no need to ask such questions ... Since most of student's are already in stressed ...

- 3 years, 9 months ago

Haha! XD Except the commerce ones.

- 3 years, 9 months ago

Yes bro But I think Brilliant is usefull for only Science student's ...

- 3 years, 9 months ago

Arts wale log ko to aap chhor hi diye :P

- 3 years, 9 months ago

Do they exist?

- 3 years, 9 months ago

Of course they do. I haven't seen one in real life, but I'm sure they exist... somewhere...

- 3 years, 9 months ago

This is sheer nonsense about what is commented about arts students. That is a subject! After all, Humanities is the most difficult subject as far as I am concerned. I have seen a lot and some of them are great. Maths and Science are not the ends of life, they are just 2 illusions created by parents.

- 3 years, 9 months ago

When did anyone say anything negative about Arts students?

My comment referred to the fact that not many students take Arts

- 3 years, 9 months ago

"Arts wale log ko to aap chhor hi diye :P" I don't think that's my comment/

- 3 years, 9 months ago

What is negative in that? You do understand Hindi, right? I said "you left out the Arts people" in case you don't.

Karan Shekhawat said every 17/18 year old gave the JEE. Pranjal replied that Commerce students were an exception. I said Pranjal had also forgotten about Arts students in his exception.

- 3 years, 9 months ago

Yes bhaiya I thought that there were going to be two papers but came to know now that for B.Tech students there is only one paper.

- 3 years, 9 months ago

Ok , I Understand!

- 3 years, 9 months ago

How was the paper ?

- 3 years, 9 months ago

It was overall easy.

- 3 years, 9 months ago

so how much are you expecting!!

- 3 years, 9 months ago

Has anyone tried the problem :

A red LED emits light at 0.1 watt uniformly around it. The amplitude of the electric field of light at a distance of 1 m from the diode is :

What you are getting cause I was getting 2.45 V/m.

In VMC answer key it is written as 5.48 V/m.

- 3 years, 9 months ago

I tried and i got the same as u got.. and i am sure i am right

(Power= intensity x area)

- 3 years, 9 months ago

According to VMC answer key how much you are getting ofcourse keep the two errors notified by me in mind( rest answer key is correct I have checked it thouroughly)

- 3 years, 9 months ago

I dont think the number of non trivial solutions is correcr in vmc answer key

I am getting 298 as per it

105 in phy 101 in math 92 in chem

As per vidya mandir

I expect no major deviations from this

- 3 years, 9 months ago

I was getting '3' in that question. Idk why is answer 2 in Reso's answer key.

- 3 years, 9 months ago

I too got 3 solutions. And i made sure that no roots were repeating... hope i get marks there

- 3 years, 9 months ago

Allen's answer key says '2' as well.

- 3 years, 9 months ago

Did you back substituted the values?

- 3 years, 9 months ago

No but i dont see why we have to. Determinant 0 means non trivial

- 3 years, 9 months ago

I mean just for checking it up.

- 3 years, 9 months ago

There are two solutions indeed one root is repeated, also I have verified by putting each root into the original equations.

I may be wrong though you two people look just confident .

- 3 years, 9 months ago

U are right i just checked that 1 is repeated

Shit so no 300 up for me i suppose, i must work harder for advanced

- 3 years, 9 months ago

Is 3 hours sufficient to complete the paper ?

- 3 years, 9 months ago

time is never a problem in most cases. even i being a dumb attempted it in 2hr 30 minutes.

- 3 years, 9 months ago

@Karan Siwach how much are you getting?

- 3 years, 9 months ago

@Mahimn Bhatt; with vidyamandir's latest answer key, I am getting 267.

Could have easily got near 300 if there were less silly mistakes done.

MY SILLY MISTAKES

1)I marked 6/2 as 6, was knowing my mistake but couldn't correct it.

2)marked (-2,-1) as (2,-1).

3)in question of calculating number of points inside the triangle, i was thinking in my mind that the side points are not to be included, but still calculated 40 more points in a hurry or some other mind state.

4)took 1,1,3 as three different solutions.(not understanding why I didn't saw that 1 is repeating)

5)in properties of triangle question, took ABC in opposite manner.

6)in physics question, where 2 boys throw stones up, i was knowing my mistake but couldn't correct it.

7)physics problem, of inelastic collision, while conserving momemtum and calculating change in energy took different total masses in both cases i.e. 3m in momemtum equation while 4m in calculationg loss of energy.

8)in chemistry, calculated 54mg for 3g of charcoal, but missed that the answer was to be given for 1g of charcoal.

- 3 years, 9 months ago

thats a great score indeed you will rock in advance..!

- 3 years, 9 months ago

Yes time is not a problem, not for jee main, atleast not this year. But accuracy is a factor where i got hit

- 3 years, 9 months ago

Is quick calculation needed ?

- 3 years, 9 months ago

298 is a very good score ...

- 3 years, 9 months ago

2 is the right answer. '1' comes out as repeated root.

- 3 years, 9 months ago

I am probably getting somewhere 300+ or even 310+. Thankfully didn't make many silly mistakes!

- 3 years, 9 months ago

@Azhaghu Roopesh M @Purushottam Abhisheikh @Deepanshu Gupta @Pranjal Jain please share your marks !

- 3 years, 9 months ago

275... $$\ddot\cry$$

Those are right on my profile as status.

- 3 years, 9 months ago

Do you have deepanshu's contact number?

- 3 years, 9 months ago

Yes Bhaiya,I saw.BTW which set did you get?

- 3 years, 9 months ago

I got 254.

- 3 years, 9 months ago

Hey! I didn't check my marks for a long time. So, here it is: total: 303. (P,C,M)=(103,110,90).

- 3 years, 9 months ago

@Raghav Vaidyanathan Which coaching centre do you attend?

- 3 years, 9 months ago

I go to FIITJEE. It's actually an integrated program with school for class 11 and 12 called PINNACLE.

- 3 years, 9 months ago

@Raghav Vaidyanathan Thanks a lot

- 3 years, 9 months ago

I can bet that you made many silly mistakes in Maths and that is why you lost marks and not because you did not know!Right?

- 3 years, 9 months ago

You are right.. :/ those distance questions of 3-D geometry... and the area question.. poof!

- 3 years, 9 months ago

I knew it!Anyway awesome marks!Good luck for Advanced!

- 3 years, 9 months ago

Thanks!

- 3 years, 9 months ago

bro, dont you think it will be ion dipole for inverse cube force? and yes , awesome marks

- 3 years, 9 months ago

Yes, in resonance key it is ion-dipole? What is wrong?

- 3 years, 9 months ago

VMC says its hydrogen bond, phew, so i got +5 extra :D thanks

- 3 years, 9 months ago

I also tick H-Bond .... But does this is written in NCERT ?

- 3 years, 9 months ago

no, you gotta derive it, you see the field due to one charge varies as k/r^2

so kq/(r)^(2)-kq/(r+d)^(2)= force by charge on dipole = (approx) -2kp/r^3 (using calculus, where p is dipole moment (qd))

- 3 years, 9 months ago

ohh sorry It doesn't click me .. Thanks !

And Saketh what's is your plan of next 2-3 day's ?

and after that what about JEE Adv* ... how will you prepare .... joining crash course or not ...? and etc etc .... Please tell if u don't mind Thanks Sir :)

- 3 years, 9 months ago

dont 'sir' me bro, not yet,

No plans, get started on JEE advanced, work every chapter, i dont think theres a crash course facility in my neighbour hood, but pathfinder will take some jee advanced mock tests,, also my tution teachers and i shall test myself

- 3 years, 9 months ago

okay bro ... :) Means you will starts from tommorow with full speed :P ... ? No break ? I mean not an single entertainment , Like movies (Even fast & furious 7 ? :P) etc... ?

- 3 years, 9 months ago

Indeed i will, fortunately i am not interested in many movies (and i hate fast and furious series) , also i think pure advanced prep will be just as entertaining for us, keeping us on the edge

- 3 years, 9 months ago

Thanks! I wrote ion-dipole since dipole was mentioned... although I'm now doubting myself... hmm :/

- 3 years, 9 months ago

VMC has corrected the answer, its ion-dipole.

- 3 years, 9 months ago

I completed

Maths - 50 mins

Chem - 40 mins

At last

Phy - $$\infty$$

- 3 years, 9 months ago

U must have solved phy accurately???.... Cuz u gave 1.5 hr for it.

- 3 years, 9 months ago

@Krishna Sharma ,please tell how much marks are you getting ?

- 3 years, 9 months ago

Pretty bad I can't tell -_-

- 3 years, 9 months ago

Unfortunately I didn't looked at watch so carefully. Also I solved questions randomly and in no pre-selected or particular idea. But I think I gave 1 hour to maths, 45 minutes to chem and 1 hour to physics

- 3 years, 9 months ago

- 3 years, 9 months ago

Completed chemistry in - 30 min.

Then completed maths in 1 hr.

Remaining time for physics.

- 3 years, 9 months ago

best of luck for jee advanced.....I am sure you, ankur and many others will make our centre proud...

- 3 years, 9 months ago

Strategical!!:) did 1.5 hr make a huge difference in physics????

- 3 years, 9 months ago

Well 1.5 hours for physics was not strategical but I was able to complete other parts in that much time. But even in 1.5 hours I had to leave 7 questions.

- 3 years, 9 months ago

I am starting to get the feeling that I don't belong here . ha! Getting only 200 ,mainly due to phy . hope advanced goes well. Anyways congrats @Ronak Agarwal ,@Mvs Saketh N other such brillianters !!!

- 3 years, 9 months ago

- 3 years, 9 months ago

Expecting 315. Discussed the paper with Teachers in Coaching

This is expected score Still has chance of this changing after CBSE releases it's answer key.

Would be getting close to 330 if I have not commited silly mistakes.

- 3 years, 9 months ago

Congrats ! That's a great score. @Ronak Agarwal

- 3 years, 9 months ago

Congratulations :)

- 3 years, 9 months ago

That really is a Great Score! Congrats! @Ronak Agarwal

- 3 years, 9 months ago

Amazing

- 3 years, 9 months ago

Congrats !

- 3 years, 9 months ago

Guys, @Ronak Agarwal @Pranjal Jain : Could you tell me what books you followed/ found nice for Physics &Chemistry ? Thanks.

- 3 years, 9 months ago

For me I did only coaching material.

- 3 years, 9 months ago

I'm shocked. You're really AWESOME then.

- 3 years, 9 months ago

Don't forget the net, and if theirs one book I really liked is the irodov.

- 3 years, 9 months ago

Sure. I was actually looking for books that helped you build concepts etc ..

- 3 years, 9 months ago

Then How did you know so much things not needed for jee?Like your integration skills are just awesome using some really awesome functions,double integrals etc

- 3 years, 9 months ago

Congrats ! That is awesome indeed

- 3 years, 9 months ago

Its really a "brilliant" score.I am just getting 250.....

- 3 years, 9 months ago

Congrats ! That's a great score.

- 3 years, 9 months ago

ita really a "brilliant" score.i just managed to score 250

- 3 years, 9 months ago

Congratulations!! You nailed it.

- 3 years, 9 months ago

Expecting around 305-310 with resonance answer key.

- 3 years, 9 months ago

Amazing Man !

- 3 years, 9 months ago

Really?I was kind of expecting more.

- 3 years, 9 months ago

Yes, This is awesome @Ronak Agarwal is getting same marks as you.

Is time enough ? Is speed calculation required ?

- 3 years, 9 months ago

My view is that speed calculations may be necessary in in our initial stages of preparation,towards the end I think accuracy will play a much bigger role.

- 3 years, 9 months ago

@Pranjal Jain Where is deepanshu bhaiya.? And see his profile doen't open it says 404 page not found .This is not good.

- 3 years, 9 months ago

OMG!Bhaiya you are right!Last time I saw his account,his status was "I quit Brilliant!".After that he probably deleted his account :(((

- 3 years, 9 months ago

- 3 years, 9 months ago

No I can find his questions. here.

- 3 years, 9 months ago

But his account is deleted. You can ask @Satvik Golechha

- 3 years, 9 months ago

He wrote this status before deleting his account. Actually there was a time span of about 2-3 hours between these activities.

- 3 years, 9 months ago

but his sets are unavailable!!

- 3 years, 9 months ago

Was it before mains or today after .?

- 3 years, 9 months ago

Afterwards bhaiya!

- 3 years, 9 months ago

@Adarsh Kumar - did you see his account last time after or before JEE main ?

- 3 years, 9 months ago

I m very much tensed for him.I m scared really. It is anawkward and mixed feelings

- 3 years, 9 months ago

Afterwards bhaiya,in evening I saw.

- 3 years, 9 months ago

Oh shit.

- 3 years, 9 months ago

I just saw it 2 hours ago. But now it is deleted. :(:(((((((((((

- 3 years, 9 months ago

oh , that is really sad, i hope everythings all right with him, hope its just a temporary lapse

- 3 years, 9 months ago

Me too. I have learned a lot from him. I hope he come back soon. :(:(

- 3 years, 9 months ago

Yeah But i m scared about his status "I quit brilliant".

- 3 years, 9 months ago

We can see his status go to any of his problems and hover your mouse on his name.

- 3 years, 9 months ago

I saw that earlier too. I thought he quit brilliant to prepare for Advance but now he has deleted his account. I tried to find the time when he wrote this status by checking his activities but I didn't find anything. I think he deleted them too.

- 3 years, 9 months ago

I hope mains doesn't have a permanent impact on him :'(

- 3 years, 9 months ago

Well i hope its not because of mains it should be coz of advance preps i hope.

- 3 years, 9 months ago

But advance preps won't bring about a crash landing in his brilliant account.

- 3 years, 9 months ago

Just B+.

- 3 years, 9 months ago

Whatever may be the reason, let's hope that he returns to brilliant with a bang!

- 3 years, 9 months ago

What steps would you all suggest for me for JEE ? I am a Class 10 passout in 2015 aspiring for JEE. I have around 15-20 days time before my coaching classes begin .

This is an earnest appeal. Please do not downvote if you dislike my comment.
