While introducing Applied Mathematics course in 2020, CBSE mentioned that in higher education, mathematics is frequently employed as a complementary subject in the fields of economics, commerce, social sciences, etc. According to observation, students who pursue Commerce or Social Science in college may not be able to use the senior secondary mathematics curriculum designed for science topics. In order to give students useful Mathematics skills that may be applied to areas other than the physical sciences, one more elective course in the mathematics curriculum for senior secondary schools is established with this in mind.

Although the course is relatively new, there’s no reason to worry.

FAQ

How is Applied Mathematics different from Mathematics in CBSE Class 12?

Mathematics is not just relevant for Physics, Chemistry students but it is also widely used in field of Economics, Commerce, and Social Sciences. CBSE observed that Mathematics syllabus in class 11th and 12th (meant for Science subjects) is not exactly appropriate for the students who wish to pursue Commerce and Social Science-based subjects for further education and professions. Applied Mathematics was, thus, introduced as one more elective course that is specifically developed for 11th and 12th classes.

Which is the most important unit in CBSE Class 12 Mathematics?

CBSE Class 12 Mathematics constitutes of 6 units. Calculus is the 3rd unit in the syllabus and has a total weightage of 35 marks out of 100. Thus, Calculus can be said tobe the most important unit in CBSE Class 12 Mathematics.

Should I practice Algebra or Calculus for CBSE Class 12 Applied Mathematics?

Both Algebra and Calculus are a part of CBSE Class 12 Applied Mathematics syllabus. However, Algebra constitutes of only 10 marks in the overall assessment but Calculus constitutes of 15 marks. That makes calculus more scoring for you.
