CBSE Class 12 Syllabus of all subjects
Class 12 CBSE Syllabus 2019-20 for All Subjects | CBSE Exam Pattern | Chapter-wise Marks Distribution
Every year CBSE conducts board examination for class 10th and 12th. Class 12 CBSE Syllabus 2019-20 is released by Central Board of Secondary Education. But Class 12th Exam Pattern has been changed and the new pattern and marking scheme is introduced for the session 2019-20. So in this article get to know the changes for CBSE CLASS 12TH Exam Pattern with the marking scheme and syllabus.

CBSE Exam Pattern of Class 12

 
Internal Assessment Earlier the internal assessment was not considered for all subjects. But in March 2020 exams, it is mandatory for all the subjects. From now 25% marks are allotted as internal assessments [20 out of 100]. So from March 2020 exams, the final exams will be conducted for 80 marks. However, some fine arts and science stream subjects will follow the same ratio of 70-30.
Multiple Choice/Objective Type Questions Recently MCQs or objective type questions are included in all the exams. CBSE will ask 25% of the questions as MCQs. So it is clear that at least 20 marks in each exam are covered by these objective type questions. Rest marks will be covered by the subjective and theory questions.
Choice in Questions As per the trend of 2019, CBSE will give option for choice to the students in 33% of the questions.
  So, here is the Class 12 CBSE Syllabus 2019-20 for All Subjects with Unit wise weightage:
