CBSE Class 12 Board Exam 2023 Post Paper Analysis - Biology (16th March)

The Central Board of Secondary Education (CBSE) conducted the Biology exam for students of Class 12 today, 16th March 2023, following a good gap of 5 days after the Major Mathematics paper. So students got sufficient time to prepare for the Biology paper. It was very much needed as there were a couple of changes in the question paper pattern this year. It's important to note that Biology is considered one of the crucial subjects for students planning to appear for NEET. 

CBSE Class 12 Biology Paper 2023 is over, and the students had varying reactions to the paper. Some found it difficult, while others barely felt any challenge. The questions were primarily straightforward, and there was nothing too tricky except for a few questions. Overall, the Biology paper was of moderate difficulty level. 

Question Paper Pattern

For this academic year, 2022-23, CBSE followed the rationalized syllabus released on its official website. After the term-wise pattern adopted during COVID, CBSE returned to its old paper pattern for this academic year. However, the typology of questions and the internal choices within the paper were significant areas of change. So, let's first see the paper structure before moving on to paper analysis. 

The CBSE Class 12 Biology paper was 70 marks, and the time allotted for the exam was 3 hours. The question paper comprised 33 questions distributed over five sections A, B, C, D and E. All questions were compulsory. 

There was no overall choice in the question paper. However, internal choices were provided in one question of two marks, one question of three marks, and all questions of five marks. Students were expected to attempt only one of the alternatives in such questions.

Here we decode the CBSE 12 Biology 2023 Board paper Series EF1GH/3-Code 57/1/3-Set 3.
