Latest Update on CBSE Class 10 Science Syllabus 2024-25

Since class 10th is when students take their first board examinations, it can be a challenging year for them. The Board has created the CBSE Class 10 Science Syllabus for the 2024–2025 academic year to adhere to certain requirements. Completing the Class 10 Science Syllabus is crucial for students to grasp the primary and peripheral subjects covered in the course. The syllabus also outlines the distribution of marks for assignments, projects, practicals, and each unit. Students may use the CBSE Class 10 Science Syllabus 2024–25 to schedule their study sessions and be ready for the approaching board examinations.

The syllabus for the 2024-25 academic year has been released and we were prompt about predicting the changes. Below, we have provided you with a simple analysis of the Class 10 Science Syllabus, along with:

  • PDF download -> latest and past year syllabus for CBSE Class 10 Science
  • Competency Focus -> What is new
  • Detailed analysis -> Deleted and added topics/ chapters
  • Lab exercises -> List of all 2024-25 practical

Class 10 Science and Class 10 SST can be studied together as both subjects are somehow related to each other. Students can check the chapters in the Class 10 science syllabus & also check the topic-wise division in SST Syllabus Class 10.

Tips for Preparing the Science Syllabus for CBSE Class 10

The Process of Learning

  • Learn scientific concepts through applications and examples.
  • Pay close attention to understanding each subject's underlying theory.
  • Instead of memorizing formulae, understand their meaning, purpose, and origin.
  • Instead of depending just on facts you have committed to memory, solve challenges using your comprehension.

Study Regularly

  • Make it a habit to study every day, even if it's only for a short while.
  • Regular, brief study sessions work better than last-minute cramming the night before the test.
  • To achieve greater recollection, divide the course into digestible chunks and cover each one progressively. 

Effective Time Management

  • Completing the CBSE Class 10 Science Exam requires a strong grasp of time management.
  • Set aside time in your study sessions to focus on each subject.
