Important Changes in CBSE Class 12 Exam Pattern 2023

As per the new circular, CBSE class 12 syllabuswill not be reduced this year. In AY 2022-23, there will be around 25-27 questions in Science subjects i.e. Physics, Chemistry, Biology and Mathematics. The detailed changes are as follows:

• Multiple Choice Questions in English Language and Literature: In English Language & Literature, there will be multiple choice questions, fill in the blanks and synonym/antonym from unseen passages. 
• Assertion and Reason Based Questions in Biology: The board has eliminated the multiple-choice questions from Biology and has framed assertion and reason-based questions. There will be around 5 one-mark questions but it will be more of descriptive nature. Candidates are suggested not to write answers of one word form in Biology.
