You must have a pretty vast idea about the importance of Science in the CBSE 10th Board Exam. Science also plays a major role during your higher secondary education too. If you are aspiring to go for the Science stream in the future or want to become an Engineer, you must require good conceptual knowledge as well as marks in CBSE 10th Science.

Students must ensure that they go through the complete Science Syllabus for Class 10 CBSE to know the various topics and marks distribution. The annual examination and periodic tests will be conducted in accordance with the same.

The NCERT 10th Science Syllabus will help them in their preparation.
