CBSE Board Exam 2021: The CBSE Class 10 and Class 12 Board Exams 2021 are all set to begin from May 4. With less than a month left for the CBSE Board Exams 2021, all the candidates must solve sample papers released by the board.

Check analysis of CBSE Class 12 Physics, Biology and Chemistry Sample Paper 2020-2021

CBSE Class 12 Chemistry Sample paper analysis

Total Marks: 70

Time: 3 hours

Section A

Total Questions -16 (22 questions including sub parts) | Marks: 22

First two questions are case based questions or journal based with four MCQs or Assertion Reason type questions each. Rest questions are MCQs and Assertion Reason from curriculum.

Section B

Total Questions — 9 | Marks:18

Each question carries 2 marks. There are 3 internal choices. Numerical based questions are included in this section.

Section C

Total Questions — 5 | Marks — 15

Each question carries 3 marks. There are 2 internal choices. Inorganic Chemistry reasoning-based questions are included in this section.

Section D

Total questions — 3 | Marks — 15

Each question carries 5 marks. Every question has internal choice. Each question has two parts and division of marks vary from question to question. One question each from Physical, Inorganic and Organic Chemistry is included.

Analysis:

Total questions are 33 (39 including subparts). There are no Very Short Answers carrying 1 mark this year. Instead, there is a greater number of MCQs and Assertion Reason questions. Passage based question is replaced by a slightly tougher case-based question which requires a deeper understanding of organic chemistry topics to attempt question successfully.

If you do not waste much time in attempting MCQs and Assertion Reason based questions, exam is neither too lengthy nor too short.

Total Marks:70

Time: 3 hours

Section A

Total Questions — 16 (22 including sub parts) | Marks 22

This section includes ten Very Short Answer type questions, four Assertion Reason from Curriculum, eight case based MCQs or Assertion Reason questions. There are three internal choices overall in this section.

Section B

Each Question carries 3 marks. There is one internal choice.

Section D

Total Questions - 3 | Marks 15

Each question carries 5 marks. There are three internal choice.

Analysis:

Case-based questions were from ecology and genetics. It is important to focus on these topics when preparing for Section A. There was one diagram labelling based question in section D but there was no direct diagram drawing question. Students must remember to draw diagrams wherever necessary as is clearly mentioned in the instructions.

The sample paper shows some higher-order thinking skills questions which require a deeper understanding of topics. Assertion Reason-based questions are a new addition to this year's biology pattern and require extensive practice.

Analysis:

Section B included two case-based questions from Electric Charges and Optics respectively. It will be wise to devote time to these topics when preparing for this section. Section E had questions from Electric charges, Electric Current, and Optics with proper internal choices.

Overall, the student must practice assertion reason-based questions to save time for short answer type questions and long answer type questions. A sample paper can be considered a bit lengthy, so proper time management is required between sections.
