The CBSE Class 10 Science Syllabus has been designed keeping in mind the developing mindset of the students. The Science syllabus has not only been kept competitive to keep CBSE students ahead in the competition, but has also been packed with information that the students find very useful in while appearing for entrances and perusing higher studies. Upgraded to CCE format in 2011, the new CBSE syllabus helps a lot in improving the performance of the students. With projects and workshops the CBSE syllabus also helps in developing the presentation and analytical skills among students.
