From the current academic session CBSE’s remodeled assessment structure for class 10 comes in action according to which the dual scheme of examination for class 10 goes discontinued, making the CBSE Class 10 Board exams mandatory. The new assessment scheme will have an 80 marks component for class 10 Board examination in all scholastic subjects along with a 20 marks component of Internal Assessment (IA). IA comprises Periodic Tests (PT) with weightage of 10 marks, Notebook Submission of 5 marks and Subject Enrichment Activities of 5 marks.
