CBSE XII - Mathematics @ 2016

This is to all class 12(CBSE) students. How was your maths paper?

You can discuss about the paper here.

I feel the paper was lengthy. I lost 12 marks because of it. But I'm sure about the rest 88 marks.

What are your views about the paper?

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.

I wouldn't say it was hard, (as most people are complaining on the cbse website), but without a doubt lengthy. I had left some questions which I hadn't seen before for the end, so that I wouldn't waste time thinking about it. The one hour left bell rang when I had about 8 large questions left so, I had to rush everything. Messed up two questions worth totally ten marks and I'm not sure if the other final answers are right as I didn't get time to recheck the paper. Did manage to scribble together atleast something for each question. So hopefully some marks for attempting.

Just lengthy, really lengthy. (Outside Delhi)

Do not worry my comrades. My big bro gave his board examinations last year. He shared his experience of his friends who did not attempt the paper worth 13-15 marks and yet scored 90+ (ya that's true. Believe me!!)

So just cheer up, JEE is on all the best for its preparations $\huge \ddot \smile$

neelesh vij - 5 years, 3 months ago

Surely true! CBSE people are strange... Those who left got 90+ and those who did whole didn't get 100!!!

Akul Agrawal - 5 years, 3 months ago

While solving a limit problem (continuity and differentiability) I applied le hopital's rule which is not taught in cbse math. My colleagues struggle with It , and they were not familiar with the rule. Will cbse give marks for the rule I applied to solve it.

Syed Shahabudeen - 5 years, 3 months ago

I don't think so. You could've done it like this:

$\lim _{ x\rightarrow 0 }{ \frac { \tan { x } -\sin { x } }{ { x }^{ 3 } } } =\lim _{ x\rightarrow 0 }{ \tan { x } \left( \frac { 1-\cos { x } }{ { x }^{ 3 } } \right) } =\lim _{ x\rightarrow 0 }{ \tan { x } \left( \frac { 2\sin ^{ 2 }{ \left( \frac { x }{ 2 } \right) } }{ { x }^{ 3 } } \right) } \quad =\frac { 1 }{ 2 }$

You are likely not to be awarded any marks for it. CBSE marking scheme doesn't "recognize" this method,and shall be treated as wrong.

@Abhineet Nayyar @Gautam Sharma @Mayank Singh @Sachin Vishwakarma please comment.

Aditya Kumar - 5 years, 3 months ago

Outside delhi or inside delhi??

Me inside

I didn't find it lenghty

Mayank Singh - 5 years, 3 months ago

Mine was outside Delhi. One of my friends(not a JEE aspirant) in Delhi told that the paper was tough not lengthy. So that won't matter much for JEE aspirants like you.

Aditya Kumar - 5 years, 3 months ago

But for jee aspirants too.. there was no time to think as paper was lengthy.

Akhil Bansal - 5 years, 3 months ago

@Akhil Bansal – Yes for those who were outside delhi, they face time problem.

Aditya Kumar - 5 years, 3 months ago

It was quite fair paper.. Just had to think twice before scaling the lpp graph. (outside delhi)

Rohit Ner - 5 years, 3 months ago

Yeah the paper was too lengthy ... I finished it in last second :-).. (Outside Delhi)

Rishabh Jain - 5 years, 3 months ago

I left around 20 marks. Ya it was lengthy. Some other factors also affected my paper. Overall , I found it a bit lengthy. Let's hope that cbse understand and we get some grace marks. I am highly depressed. :(

Sachin Vishwakarma - 5 years, 3 months ago

Brother CBSE people aren't good people. They don't have any feelings. Don't expect grace marks.

Aditya Kumar - 5 years, 3 months ago

Hmm. Now it decreased my interest in maths. I feel like i am not suitable for maths if i couldn't solve the paper. :'( Really feeling bad. Physics had already gone bad. I had no hope for chemistry. I had all the hope with maths but it also made me sad. Now i can expect a percentage of 85 - 90. :(

Sachin Vishwakarma - 5 years, 3 months ago

@Sachin Vishwakarma – Don't lose hope.. If you are good at maths it will surely help you in JEE Adv. which is the most important exam in coming months... Although I finished my maths paper in last seconds but in rest of the subjects my situation is same as you.. And these boards surely gonna spoil my JEE Mains Rank too ... :-(

Rishabh Jain - 5 years, 3 months ago

@Rishabh Jain – Only JEE marks can take us out of this condition. Let's see.

Sachin Vishwakarma - 5 years, 3 months ago

@Sachin Vishwakarma – Brother marks doesn't determine one's ability to achieve something. Eg. Michael Jordan was not selected in his school basketball team. Didn't he succeed? That's the similar case with us. Talking about IIT-JEE, you just need 75% to get into IIT. So work hard for JEE-Adv.

Aditya Kumar - 5 years, 3 months ago

@Aditya Kumar – Hmm. Now i feel less depressed coz " A single piece of paper can't determine my future ". :) Let's work for JEE. Thanks for motivating me.

Sachin Vishwakarma - 5 years, 3 months ago

@Aditya Kumar – So you're saying that you're comparable to Michael Jordan? xD

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – Consolations would be accepted peacefully. LOL

Gautam Sharma - 5 years, 3 months ago

@Mehul Arora – No jokes here please.

Aditya Kumar - 5 years, 3 months ago

@Aditya Kumar – Oh c'mon! Lighten up people! I agree it is not very easy to take, But, It is not the end of the world. Now get all of your brains back and start preparing for JEE, and get into the top 100s. @Sachin Vishwakarma @Aditya Kumar @Akhil Bansal @Gautam Sharma

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – I'm as light as ever :)

Aditya Kumar - 5 years, 3 months ago

@Aditya Kumar – yeah lighter than ever. (weird trick to lose weight in one night .I m gonna advertise it)

Gautam Sharma - 5 years, 3 months ago

@Gautam Sharma – Nice going on the weight loss, @Aditya Kumar @Gautam Sharma

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – Hey mehul in which class you are ?

Chirayu Bhardwaj - 5 years, 3 months ago

@Chirayu Bhardwaj – @Mehul Arora is a retired old person.

Aditya Kumar - 5 years, 3 months ago

@Chirayu Bhardwaj – I think Aditya did my job. My age is fake, I am actually 56 years old.

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – No chance u r 65.

Aditya Kumar - 5 years, 3 months ago

@Aditya Kumar – Oh cmon

Not 65. I have 9 years to go for that.

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – Really ???? :O :O

Chirayu Bhardwaj - 5 years, 3 months ago

@Chirayu Bhardwaj – Yes @Chirayu Bhardwaj :)

Agreed, @Aditya Kumar I do look like a 65 year old, but i am not :3

Mehul Arora - 5 years, 3 months ago

@Mehul Arora – But you look like a 65 year old.

Aditya Kumar - 5 years, 3 months ago

@Aditya Kumar – LOL xD

Mehul Arora - 5 years, 3 months ago

Grace marks are given in such cases. Trust me.

Been there, (was) given that ;)

Pulkit Gupta - 5 years, 3 months ago

I couldn't complete the Area problem and had no time to revise.

I have seen people telling that it was '15 like. Is that true?

Agnishom Chattopadhyay - 5 years, 3 months ago

I had solved previous year paper and it took around 2 hrs 35 min. This year paper was quite lengthy. '15 was tricky and fun to solve but '16 was boring and lengthy.

Sachin Vishwakarma - 5 years, 3 months ago

My friends who had solved last year's papers told that this year it was tougher.

Aditya Kumar - 5 years, 3 months ago

I am also feeling bad. I wasn't able to attempt 16 marks paper. Cbse has gone mad.
I also feel that paper was tricky.
(Delhi)

Akhil Bansal - 5 years, 3 months ago

I found paper very boring. I was feeling sleepy during the examination which lost me 12 marks.

Aditya Kumar - 5 years, 3 months ago

Paper was very lengthy although i attempted whole paper.No time was left for revision and i m quite confident with my methods but only god knows about calculations.That probability distr. ques beated the hell out of me.

Outside delhi

Gautam Sharma - 5 years, 3 months ago

I knew how to do the but time was the biggest problem.

Aditya Kumar - 5 years, 3 months ago

Delhi paper didn't seem to be lengthy or tricky. But I did a silly mistake of a "-" sign! no idea how many marks mad CBSE people would cut for it!

Akul Agrawal - 5 years, 3 months ago

It last 45 min It was looking impossible to attempt all the paper (reflecting lengthiness of paper) but I managed to do it and expecting 90+ marks .(ANY 100/100 here)

There is not a single sec left for revision of paper . I am not good at binary operation and LPP both together suck my 10 marks (I hope I am only person whose was unable to solve these two) , but about rest of paper I am confident . If anyone have answers key , please tell me .(Outside Delhi)

Now it's time for JEE MAINS-2016 final revision

Yash Dev Lamba - 5 years, 3 months ago

@Aditya Kumar Which board should I keep for 11th ? CBSC , ICSC or state board ? Currently I am in CBSE board appearing for 10th boards.

A Former Brilliant Member - 5 years, 3 months ago

See it depends on your preferences. Since you live in Maharashtra I recommend you to join CBSE as Mahrashtra HSC sucks. Their physics paper was pathetic. No action is being taken over that. But for us in CBSE there are wide range of discussions over this issue. So that's a boon.

Aditya Kumar - 5 years, 3 months ago

Physics paper was tough or questions asked were wrong ? Thanks !

A Former Brilliant Member - 5 years, 3 months ago

But dont worry my friends....CBSE Has said that the paper will be checked very lineantly!!! Ao dont worry

Aryan Vyas - 5 years, 2 months ago

Can anyone post the paper

pranshul srivastav - 5 years, 3 months ago

I FOUND THE PAPER HARD , I WAS GETTING WRONG ANSWERS IN MATRIX , IT CONSUMED MY MUCH TIME..!!!
