Science is a very important subject as far as the CBSE class 10 curriculum is concerned. Students can score good marks in this subject if they prepare well and get their concepts clear. To initiate the preparation of science subject, the students should know and thoroughly understand the new CBSE 10 Class Science syllabus 2023-24.
In the syllabus, the students can find out the topics and sub-topics they need to study in an academic year. The complete science paper of CBSE class 10 will carry 100 marks out of which 20 marks (10 marks for each term) will be of internal assessment. Theory is of 80 marks divided into 40 marks each for Term I and Term II. Go through this post, to find complete details related to the CBSE Class 10 Science syllabus 2023-24.
