What ??? Can anyone explain why the pics are tilted ??? It was just fine when I "Previewed" it !

Sorry for the trouble , but pls open the image in a new tab to view it !

Since there is so much of protest against the "hardest" maths test in a decade, is this the same paper? I don't know if the paper is same all over the country but here, there are many protests, so just asking - are the protests worth?

*I haven't even given a glance at it, so I cannot judge.

- 6 years, 2 months ago

Well , the paper from the South (India) was quite easy , or so it seemed from the link that Raghav provided . But this one that I have posted is quite lengthy . You can try it out , it's not that difficult , just that it involved THINKING, something that's not much prevalent in CBSE Schools and Students these days .

THINKING something that's not much prevalent in CBSE Schools and Students these days .

xD

- 6 years, 2 months ago

Cool ! Did you take a screenshot of my comment and repost it ? How did you do it ?

Also I have added the 2nd last page .

- 6 years, 2 months ago

Just use ">" at the beginning of a line.

- 6 years, 2 months ago

Let me check it out !

Hi

- 6 years, 2 months ago

- 6 years, 2 months ago

Yes I did. Looking at pages sideways was annoying.

- 6 years, 2 months ago

Then would you be so kind to upload the 2nd last page too !

Thanks :)

- 6 years, 2 months ago

Done. I've edited the link in my original comment.

- 6 years, 2 months ago

Thanks :)

- 6 years, 2 months ago

just that it involved THINKING, something that's not much prevalent in CBSE Schools and Students these days .

I kind of find it odd that people find themselves right in complaining about the difficulty of the paper. I mean, it's supposed to be an exam to test the candidate's aptitude/proficiency in a subject, so, shouldn't it be difficult? But I'll give you this, they should not have amped up the difficulty so much without informing anyone, even If the change was gradual, it would have been okay. I'm against there being sets which are totally easy though. That just defeats the purpose of a fair exam... but yeah.. it's already happened, nothing to do about it.

- 6 years, 2 months ago

These exams are mainly NOT to test your ABILITY. Even avg student must be able to score 80. To prove your mettle, you have the JEE /BIT exams. Imagine the plight of the poor arts/medicine/commerce students who mayn't be as good as the JEE prodigies. I strongly disagree with @Mvs Saketh calling them idiots.

- 6 years, 2 months ago

Don't take Mvs Saketh comment seriously he didn't meant it. But I agree that the education system must be changed, and this is a positive step towards it.

People simply mugging up things must be punished like this.

- 6 years, 2 months ago

Seriously ? "Punished" ?

But I guess the transition of the paper style from Theoretical questions to Application based questions is finally here but just that people aren't able to accept it .

Haha , "Sach kadva hota hai !"

- 6 years, 2 months ago

And yes I repeat PUNISHED, like that only,

but I not in favour of ONLY cbse putting a tough paper, that's wrong that's not justice, I mean it directly giving the students of state boards edge over their counterparts for admission in various colledges , I believe some system ought which takes in account these factors.

This is wrong being done to ONLY cbse students they don't deserve that, Collegdes must consider the toughness various board exams.

- 6 years, 2 months ago

Yeah . The Gujarat Board has decided to be lenient in their marking this year since some students (well, their parents!) complained to the authorities . Can you believe it ?

Now they'll end up getting good ranks in Jee Mains even if his/her Jee Mains marks are same as that of a CBSE student .

Well , let's hope for the best :)

- 6 years, 2 months ago

It's not like that...This year, the marking scheme is going to be very STRICT in Maharashtra State Board though the marking scheme might be lenient in Gujarat, as you said.

You CBSE students are quite lucky to have a lenient marking scheme... I was in CBSE in class 10th and that time the CBSE was lenient in marking scheme. State board has made my life very tough and I am probably going to sink...

Also, the maths state board paper of Maharashtra was quite very difficult and some 2-3 questions were wrong which in total carried 7 marks. All questions were very tricky though and some steps were needed to remember, for instance in calculus section.

- 6 years, 2 months ago

Actually class 10 boards were quite easy and now this one was tough , the reason that caused all this controversy !

I really feel that CBSE must amend its ways of teaching students or they are going to expect a repeat of this years performance again next year .

Btw how's your JEE Prep going on ?

- 6 years, 2 months ago

It's going OK.. How's your preparation going? Also, are you practicing the papers or just going through the theory & formulae?

- 6 years, 2 months ago

Well I must say both . Also some minor topics like Dimentional Analysis , PMI , Chem in Every day Life need to be revised .

Once I am done with the revision (which is most likely by the 29th) , I'll solve at least 4 papers a day (I might sound a bit ambitious , but I've got no choice!) .

- 6 years, 2 months ago

Wait wait wait. I would love to have a long drawn out discussion on this. I strongly condemn CBSE for doing this and whosoever the paper setter is (though I am in no way affected by his/her cowardly sissy-like actions), I wish the worst for him/her. 12th grade math is easy when you look at it from boards point of view usually. But when you suddenly decide to bring about a change that involves you to not only think your asses off to get to the end of a question but also write at great lengths, its gonna be really demeaning. CBSE has NEVER been application based and never WILL be too. This is by any means a damn shameful move. It is quite abrupt , which is why i say so

- 6 years, 2 months ago

Did Saketh use the word "idiots" ? Hmm , I wonder what was going on in his mind .

- 6 years, 2 months ago

As I said he probably didn't mean it, I think he just typed it in the spur of the moment.

- 6 years, 2 months ago

You misunderstood me , I never meant it in the wrong sense . Just thinking abt the fact about how certain words when read in the wrong concept can be misunderstood to varying proportions !

- 6 years, 2 months ago

Mvs Saketh must not have meant it seriously. And I do not quite agree with you. If everyone scores really well, then what's the point of having an examination? It's easier to just give everyone a "you scored above 90" certificate and just let it be. And learning math for JEE does give students an edge in the exam, but there are "poor" arts/medicine/commerce students who are good at math too. I do find it a bit disturbing that CBSE departed sharply from the previous pattern, but I think the main problem was that the students expected an easy paper but were met with a difficult one. According to me, what happened was the result of people going through previous year papers and questions and preparing that way instead of actually trying to learn the subject. Everyone goes "where have I seen this question before??" instead of "how can I solve this??". As @Ronak Agarwal mentioned, this is a positive step towards improving the system(or so I think), we'll see...

- 6 years, 2 months ago

Everyone goes "where have I seen this question before??" instead of "how can I solve this??"

I totally agree with you on this thing . In fact just after the Maths exam , I heard some girls talking : " I am definitely going to fail in this exam . Only 3-4 questions were from RD Sharma or of NCERT Pattern "

You see , perhaps it's the way we CBSE students have been hardwired that's wrong and that should be changed and this exam was a great attempt in that direction .

- 6 years, 2 months ago

As we prepare for JEE Advance, we always train our mind in such a way such that we can think something about the new problems and solve them, and similar pattern must be followed in boards also, about learning things not mugging it up and boasting good marks in boards even that they don't deserve it.

Also papers must be such that the people getting high marks in boards must deserve that.

- 6 years, 2 months ago

Again, let me reiterate. Board exams are DIFFERENT from entrance exams. They DO NOT and are NOT supposed to test the critical thinking ability of a student for more than 10 marks. Board exams form the basis for the entrance into multifarious colleges. CBSE is not the only board in INDIA. There are 30 state boards too. This move of the CBSE is definitely going to hamper the future of the average students who SOLELY depend upon the boards to survive (as in survive the heat of the competition). This positive step should have come ONLY after introduction of HOTS questions in schools. The students must be forced to try these themselves. I know, in my school , maths teachers kept giving us HOTS questions but immediately gave answers too because most of the students were blinking. If the system has to be revamped, it has to start at the grassroot levels. If not, CBSE should stop these bullcrap "SUDDEN" changes, and that too in the final examination. Many state boards have the total as 1200/1400. , but in CBSE it is 500. This is again a matter of concern for the students. CBSE is the most hypocritical board, because they say that they encourage learning by doing, learning beyond textbooks, but they never implement it. Instead, they only force the average students to push themselves to below average levels. Sigh.

- 6 years, 2 months ago

You do have a point there. The disparity between the different boards is extremely troubling. But all we can expect now is for CBSE to learn from the thousands they screwed this year and maybe come up with a more viable plan of action.

- 6 years, 2 months ago

So what do you think about my paper ? You know , just relative to your paper , how was it ?

I consider yours as far more easier .

@Vraj Mehta , what was your paper's code number ?

- 6 years, 2 months ago

I had the same paper, and I believe this was the paper everyone is protesting about.

- 6 years, 2 months ago

If this is indeed the same paper , then I guess the protests are not valid at all . It's just a bit lengthy and only questions 22 and 23 posed a bit of challenge to me .

- 6 years, 2 months ago

Your paper is lengthier and difficult as compared to mine. It seems to be similar to the physics paper if you ask me.

- 6 years, 2 months ago

IMO, you also have to consider the fact that there is a time constraint. You can't spend a lot of time on the difficult questions. The difficulty increases because of this.

Honestly, these exams are more about speed than knowledge.

- 6 years, 2 months ago

I needed 15-20 seconds more to finish up the test. I mean I left an integral as $\int\frac{1}{1+x^2}$

- 6 years, 2 months ago

I can't see the second last page of the paper.

- 6 years, 2 months ago

Oops! Sorry , I'll add it now .

- 6 years, 2 months ago

Question 11 1st part is also on Brilliant!!

- 6 years, 2 months ago

That question is actually from RD Sharma . I think it was Harsh who posted it here .

- 6 years, 2 months ago

Ohh. I see.

- 6 years, 2 months ago

Just a suggestion, u can check ur answer over here

- 6 years, 2 months ago

- 6 years, 2 months ago

@Azhaghu Roopesh M I got the same questions (different order). Can you post a solution to $\displaystyle\int \frac{x\cos x+\sin x \mathrm dx}{x(x+\sin x)}$

- 6 years, 2 months ago

Ok , I'll do it in a while :) Also this is not the question from the paper , is it ?

Btw I had attempted the other one , since that was a simple question of Partial Fractions .

- 6 years, 2 months ago

Sorry! I read that wrong. It was $\displaystyle\int \frac{-x\cos x+\sin x \mathrm dx}{x(x+\sin x)}$

- 6 years, 2 months ago

Sorry , I have had no success with this question as of now , but I'll still keep trying :)

- 6 years, 2 months ago

Speaking about the difficulty level, I totally agree with the level of exam. None of the problem was out of syllabus. Well done, cbse! (OMG Did I just praised a govt. organisation??)

- 6 years, 2 months ago

Considering the criticism that they have experienced ,if CBSE personnel read this , they'd be left blushing :P

- 6 years, 2 months ago

Thanks guys! I am pretty sure it was one of you guys who aligned the pics correctly , since you are the only moderators to have commented here .

If it wasn't one of you guys but you know who did it , please let him know that I am thankful to him .

- 6 years, 2 months ago

I did not..
