CBSE NCERT Reduced Syllabus of Science of class 10th for 2020
CBSE Class 10 Syllabus For Science 2020: Students who are
preparing for the CBSE Class 10 board examination must be aware of CBSE Class
10 Syllabus for Science. The Central Board Of Secondary Education (CBSE)
designs the academic CBSE Class 10 Syllabus for all subjects. Having a detailed
knowledge of the CBSE 10th Class Science Syllabus will ensure students cover
the entire syllabus without skipping any chapter or concepts. In this article,
we will provide with the detailed CBSE 10th Science Syllabus. Also, students
can download the CBSE Class 10 Syllabus for Science PDF from this article as we
have provided the CBSE Science Syllabus for Class 10 in PDF format.
Science is one of the important subjects in Class 10 and it
plays a crucial role in choosing the career stream in the Class higher
secondary level. So students who want to shine in the stream of Science must
score high in the Class 10 Science. For that having the detailed knowledge of
the CBSE Class 10 Syllabus for Science is a must. Read on to find out the detailed CBSE
Standard 10 Science Syllabus.
Note that due to the outbreak of Coronavirus and subsequent closure of schools, CBSE has reduced the syllabus for Class 10 by almost 30%. In this article, we will provide you with the revised CBSE 10th Science syllabus.
New CBSE Class 10 Syllabus For Science 2020
Considering the loss of teaching time, HRD Minister Ramesh Nishank has reduced the CBSE Class 10 Science Syllabus up to 30%. The list of portions that are deleted in CBSE Class 10 Science are given below:
