CBSE Class 10 Science Syllabus 2023-2024: The CBSE Class 10 Science exam will be held on March 2, 2024 (Saturday). Science being one of the major subjects in class 10, it plays a crucial role in determining students' overall performance in the CBSE board exams. Therefore, students should leave no stone unturned to prepare well for the CBSE class 10 Science exam 2024. They should revise all the topics mentioned in the prescribed syllabus. We have provided the detailed CBSE Class 10 Science syllabus which must be followed for the 2024 exams. The board has reduced the CBSE Class 10 Science Syllabus by 30% for the last academic session and the same deletion in the syllabus is to be retained for the current academic session as well. Thus, the deleted parts of the syllabus will not be considered for assessment in AY 2023-24. Check below the link to know the deleted CBSE syllabus of Class 10 Science and also check and download the complete syllabus of CBSE Class 10 Science from this article.
