Central Board of Secondary Education (CBSE) is all set to conduct the Class 12 Chemistry 2021-22 Exam on December 14, 2021. This is another major subject exam which will be held for a duration of 90 minutes, from 11:30 am to 1:00 pm. The paper will cover a total of 60 questions out of which students need to solve a minimum of 50 questions to score the perfect score of 35 out of 35 marks. This implies that students will also receive internal choice in the question paper. This is in accordance with the newly-introduced CBSE Class 12 Chemistry 2021-22 exam pattern.
In addition to following the CBSE Class 12 Chemistry 2021-22 exam pattern, students are also expected to study only 70% of the syllabus. Due to the COVID-19 pandemic, CBSE had decided to reduce the Chemistry portion by 30%. This same syllabus has been imposed this year, as well. Read ahead to understand the deleted as well as reduced syllabus.
