Question number 31:
Assertion : sodium hydrogen carbonate is used as an ingredient in antacids.

Reason: sodium hydrogen carbonate is a mild non corrosive basic salt.

Answer given in official answer key is B
But the answer is A. Because the reason explains the assertion properly.

Question number 32
Assertion: burning of natural gas is an endothermic process.

Reason:methane Gas combines with oxygen to produce carbon dioxide and water.

the answer given in official answer key is C but the answer is D because assertion is wrong (burning of natural gas is an exothermic process not endothermic)

Question number 60:

if Power of the eyepiece lens to is 5 dioptre and it forms an image at distance of 80 cm from its optical centre at what distance should the object be.
A) 12
B) 16
C) 18
D) 20
The answer given in official key is B
If the value in this question taken is + 5 then the answer isn't coming as 16. But if the value taken here is -5 the answer comes 16.so this means that the second lens is a concave lens.but in question number 57 answer is given that both the lenses are convex.

I on the behalf of every 10th grader, request the CBSE board to please check these questions and make the necessary changes, so that the children's marks are not affected. We, students have marked correct answers but some of the answers in answer key is wrong. This is a huge loss for us. Please check these questions

I am very dejected with the answerkey which is released for code 001/1/4 for eng. There r multiple errors in it to begin with the writing sec in ques no. 20 regarding the details of the candidate to be asked for hiring a receptionist shouldn't personality, age and experience be taken into consideration as that's what really matters in a receptionist (also that is the way in which we write the ad too; starting with the type of personality needed followed by the age and experience). In ques 23 how come dress code is needed for the enrichment classes that too which are being conducted in the school itself shouldn't A option be correct for that. Coming to the literature part in ques 34 the experience which is being talked about in the extract is of the drowning incident which took place at the YMCA's pool so how come the answer is option b, I mean how did that incident enhanced his survival instinct rather it restricted him from enjoying his life so shouldn't ideally option c be the correct ans. In ques no. 37 how is the narrator feeling uncomfortable shouldn't sorry be the right option. In ques no. 40 I feel both simile as well as alliteration should be taken as the right ans as the letter 'b' and 'a' r being repeated along with the word 'like'. In ques 44 the expression "merry children spilling" I feel both option a as well as b can be correct they r absolutely similar to each other.The answers for Ques no. 46 and 49 to has error in it. I hope cbse takes this in consideration while preparing the result and takes the decision in favour of the students

Respected Sir/Madam,

I have chosen option B because that is what I thought to be the correct answer. I checked our NCERT book and I see that my answer is correct. In some social media, the answer is showing "option A". Kindly look into the matter.

Sir,
I would like draw your attention towards the cheating in class 10 maths cbse exam which held today students of Silver Grove School, Varanasi, Uttar pardesh, when they are visiting their exam centre by school bus teacher told them the answers of 16 maths question in school bus . And it's totally unacceptable how it can be sir ... The teacher name is Praveen sir from Silver Grove School (School no. 71484) and the centre no. is 847615
teacher phone number is .. +[protected]. He is biology teacher and told the answers of 16 maths question which is appearing in cbse class 10 board exam term 1 today I'm adding that teacher photo in this complaint ... and all the answers are right even students learnt all the option he had told . Plzz sir take an immediate action towards this issue.

Thanking you sir,

The marking scheme of class 12th English Core (301) which you (cbse) has released have so many errors, marks should be alloted with reference to the right answers and not this wrong marking scheme, also no student who marked answers in accordance to your wrong marking scheme should be advantaged as this would become a huge disadvantage for those who actually did well in exam.

Hello i am a student of class 12th from bhopal .
I am very disappointed on that answer key which you released...ive watched some of the youtube videos they said if cbse has done something wrong they would correct it ...but how come we students will get the surety of it? We will be always in that denial that we will be judged on the answer key of yours . And how come you people could release such a blunder key .
Which makes no sense .
And in the English cbse question paper. We students were facing multiple right answers rather than going for one...we are not words masters . We expect you people to atleast release paper that even a basic child could solve...
None of the questions matched according to the sample paper we kids did.
TOTALLY DISAPPOINTED.
DO RELEASE A GOOD AND CORRECT ANSWER KEY !

Hats off to CBSE for demoralizing the children who attempted a highly subjective subject like English (Grade 12, English Core, 2021-22) in an objective way, meddling with a multitude of ambiguous answers. This attempt would be a one of its kind in the world, as CBSE has treated this batch as their officially experimenting batch.
Whom to voice your concerns to as a parent, who feels miserable seeing the dilemma of the child, who secured a centum in English in class 10, but was really disillusioned after attempting an objective paper, which never assessed his caliber in English, rather tested how lucky he was, as the options given were all similar and ambiguous. The teachers are hardly concerned unless their own ward writes the exam. And do parents really have access to raise a complaint to CBSE?

Personal opinion and perspection based question paper.
The English paper had so many flaws in it first of all questions like(27)... SUITABLE STEPS TO IMPROVE READING HABITS... everyone has different perspectives of it how can CBSE judge a students knowledge on basis of this question and not only this in unseen passage too many questions has more than 2 options correct and SPECIFICALLY FOR Q. 23 i don't understand how CBSE will consider one of the option as answer when all answers are correct?!

Dear SIr,
I request you to please set up question papers of CBSE board as simple as possible. Being a clinical psychologist, I handled many depressed childen on Dec3rd. In this pandemic it is our duty to keep our children mentally healthy as they are not vaccinated at all, in India. Please dont make children confused and tensed . Hope you will consider my request favourably.
Thanks and regards
