The Central Board of Secondary Education (CBSE) has implemented a new policy regarding the awarding of divisions or distinctions in class 10 and 12 board exams. Instead of the Board calculating or declaring a percentage of marks, the decision to determine the best five subjects will now be made by the admitting institution or employer. It is important to note that the specific requirements for achieving a distinction may vary depending on the board you belong to. For CBSE board students, for example, it is recommended to aim for a score of 375 out of 500 in order to secure a distinction.
