CBSE Class 10 Science Syllabus

Class 10 Science Syllabus

Before preparing for the matriculation exams, it is imperative to have a look at the syllabus as it makes preparations easy and systematic. Unlike higher secondary classes where Physics, Chemistry and Biology come as separate books, in 10th class, the chapters from all three subjects are put in a single cover. In this blog, we have covered the CBSE class 10 Science syllabus in detail. 

Course Structure for Class X

The CBSE Science question paper for class 10th 2021 will have a slight variation as compared to the previous year. The question paper will contain 30 questions in total out of which 14 questions will be objective-type questions in different formats (MCQs, VSA and assertion-reason type). Each question will carry 1 mark and to know more about the CBSE class 10 Science syllabus follow the table given below:
