Deleted Topics Of Chemistry and Physics Class 12 CBSE 2021-22

Chemistry and Physics are the most vital subjects for students of Class 11 and 12 with Science Stream. While it is crucial to know the important topics from the syllabus of these two subjects, it is equally important to know the topics that aren’t a part of the extensive syllabus so that students can learn in a step by step and efficient way.


This article contains the CBSE Class 12 Deleted Syllabus for Physics and Chemistry for the session 2021-22.


As a result of the Covid-19 pandemic and lockdown, HRD Minister Ramesh Pokhriyal announced a major CBSE syllabus revision with a 30% reduction in the syllabus for classes 9 to 12.


To score better in your NCERT Class 12 Physics and Chemistry exams you need to practice the NCERT Solutions and Previous Year’s Question Papers regularly. But this won’t be enough for you if you want to be the best. For that, you have to take guidance from an Adaptive AI-enabled study engine which will provide you with unlimited Practice Sets as well as Mock Tests, Free Video Solutions, Quizzes, Live Lectures, Subject-Wise Concept Builder and so on. The SpeEdLabs App has all of these relevant features. Succeeding in the Class 12 Board Exams won’t be difficult again if you make the SpeEdLabs App your study partner. 


Here we are providing you with the complete CBSE 12th Class Deleted Syllabus for Physics and Chemistry. Thus, you will know which topics should be excluded from the study.
