The Central Board of Secondary Education (CBSE) will conduct the Class 10, 12 examinations in February for the academic year 2019. The board has already released the list of vocational subjects scheduled to be conducted during this period. To give relief to Class 10 students, the Central Board of Secondary Education has extended the passing criteria. From next year, the students need to get a minimum of 33 per cent marks in theory and practical combined to declare pass in the subject. Here is the detail syllabus of Science
