Class 10 science deleted syllabus 2022-23: Syllabus is one of the most important things if you need to score good marks in your board examinations. Being updated with the current syllabus and preparing the study flow according to the syllabus and time remaining is very important for the students. Science is a concept based subject so you need to work on all concepts in order to get good marks in this subject. If you are updated with the current syllabus it will help you to plan your study flow.
As during the current Covid-19 situation, schools and students got a major hit in their education, the level of study and the mode of study. CBSE considered all this and decided to reduce the syllabus for each class by 30% accordingly. For this examination year, the reduced syllabus will be used for preparing board examinations this academic year. Here, you will see the standard weightage of marks for each unit and the deleted topics from each unit.
