Class 12 NCERT Rationalised Chapters and Topics

Promo GIF

At Educart, we provide reduced syllabus charts for our 100% syllabus Question Banks for classes 10 and 12. NCERT has now released similar NCERT Rationalised Chapter and Topic charts for all Class 9-12 subject books. It is safe to say that this rationalised syllabus is permanent and will be followed in the coming years for board exams and competitive exams like NEET and CUET. This change has been in the works for a long time in accordance with NEP 2020, which provides instructions to take load off of students so they can indulge themselves in competency-based learning instead of rote memorisation. This is also why the syllabus has been reduced multiple times in the past couple years.

So now finally NCERT has updated all these deleted chapters and topics for Class 9 to 12 textbooks so students may not follow them for board preparation.
