CBSE Deleted Syllabus For Class 12 Mathematics: Syllabus is one of the most important things if you need to score good marks in your board examinations. Being updated with the current syllabus and preparing the study flow according to the syllabus and time remaining is very important for the students. Maths is a concept based subject so if you’re concepts are clear you can score very good marks in this subject and for that practice is the key and ultimately entire syllabus should be known so that you can practice well on the topics which is in the syllabus.
CBSE Deleted Syllabus For Class 12 Mathematics
As during the current Covid19 situation, schools and students got a major hit in their education, the level of study and the mode of study. CBSE considered all this and decided to reduce the syllabus for each class by 30% accordingly. For this examination year, the reduced syllabus will be used for preparing board examinations this academic year.
