CBSE Class 12 Term 1 2021 Post Paper Analysis- Biology (18th December)

Was the paper easy? Were most questions from the NCERT textbook? Read on to know more.

By Topperlearning Expert 20th Dec, 2021 04:16 pm

The Central Board of Secondary Education (CBSE) conducted the AISSCE Biology exam for Class 12 today, 18th December 2021, following a gap of 3 days after the significant Chemistry paper. So students got sufficient time to revise the Biology paper. This time was needed as there were significant changes in the exam structure and question paper pattern this year. Students and experts have shared their feedback, and immediate reactions have hinted at an 'easy' and 'directly from NCERT' paper

After considering all the parameters, CBSE decided to examine the Term-wise pattern for 2021-22. It is important to note that Biology is considered one of the crucial subjects for students planning to appear for NEET. So, let us take a deep dive into CBSE Class 12 Biology Term 1 paper (SSJ/2-Set4) for 2021. 

Question Paper Pattern Changes in Term 1 2021

The exam was 35 marks, and the time allotted for the examination was 90 minutes. For this academic year 2021-22, CBSE followed a reduced syllabus released on its official website. The syllabus was bifurcated separately for Term I and Term II. 

The Term I question paper comprised of MCQ type questions from the units of Reproduction and Genetics and Evolution.  

The Biology question paper consisted of three sections A, B and C. All questions carried equal marks. There was no negative marking. There were 50 compulsory questions, each allotted 0.7 marks accounting for a total of 35 marks in the paper.

Section A had 24 questions, out of which 20 were attempted. This section is the basis for the conceptual and understanding type of questions. 

Section B had 24 questions from which attempting 20 questions were must, and this section is the basis on application type, Assertion–Reason type of questions. 

Section C had 12 questions, out of which ten were expected to be solved, and this section was based entirely on Case–study based MCQ type of questions. 

To help our student readers who attempted the various questions, we decoded the complete paper along with the chapter-wise weightage and question analysis.

Graphical Analysis of Chapter-wise Marks Distribution (2021)

The chapter' Principles of Inheritance and Variation' was the most-valued chapter carrying 12.6 marks, followed by the chapters' Molecular Basis of Inheritance' and 'Human Reproduction' with a weightage of 10.5 marks and 7.7 marks, respectively. 'Reproductive Health' was the least weighed chapter accounting for just 4.2 marks in the paper.

As expected, the questions are the basis of the student's conceptual understanding. The question paper resembled the specimen paper released by CBSE, enabling students to attempt the questions with ease and preparedness.

Students' Feedback

  • The difficulty level of the questions was moderate to easy.
  • Most of the questions are the basis of NCERT textbooks of CBSE Class 12 Biology.
  • Some questions are the basis of concepts given in Class 12 Biology NCERT Exemplar.
  • All questions were asked from the Term 1 CBSE Class 12 Biology Syllabus.
  • The paper pattern was similar to the Term 1 CBSE Class 12 Biology Sample Paper.

Teachers' Feedback

  • The paper was easy and balanced.
  • The final paper resembled the specimen question paper released by CBSE.
  • Students should get 25-30 answers correct, out of the total 40 questions.

Conclusion

The CBSE Class 12 Biology paper featured questions from the NCERT syllabus. The paper was average to easy difficulty level and was quite balanced with many questions from the NCERT textbook. Some questions seemed mildly tricky but nothing out of the ordinary or complex. So most students would score around 60-70% marks on the paper. It would be fair to conclude that this paper was easy and gave students a great scoring opportunity.

Today's Biology paper was the last major board paper for CBSE Class 12 students. It is time to be stress-free and relax after months of rigorous effort and dedication. Students can now enjoy their Christmas vacations and get set for Term II exams in the New Year 2022. Stay tuned to TopperLearning for some engaging and more exam related activities for Term II!
