Science is an important subject of class 10. With a strong base of the subject, problems can be easily resolved. Class 10 Science deals with the various topics from physics, Chemistry and Biology. The syllabus of science of Class 10 has not been adapt as no new topics have been added to it by the board.
As per the new pattern, the board exam for 2021 batch will be held in two terms with 50 percent syllabus in each term.
The Central Board of Secondary Education (CBSE) on Monday declared that it has decided to rationalise the syllabus for the academic session 2021-2022 for 10th class. The board has released the term-wise syllabus based on which the board examinations will be conducted at the end of each chapter. We are providing the links to download the rationalise syllabus of all the subjects of Class 10 in pdf format.
CBSE Class 10 Science New Term Wise Revised Syllabus 2021 – 2022: Unit-wise Marks Distribution
|Unit 1: Chemical Substances – Nature and Behaviour||25|
|World of Living||23|
|Effects of Current||13|
The syllabus for board exam 2022 will be rationalised similar to that of the last academic session to be apprise in July 2021. For academic negotiations, however, CBSE schools will follow the modules and syllabus released by CBSE.
CBSE Class 10 Rationalised Syllabus 2021-2022 includes some very important examination details which students should go through carefully for the preparation of their exams in a right way. Efforts will be made to make internal assessments of practicals or project work more acceptable and well founded as per the guidelines and temperance policy to be declared by CBSE.
