Hii!
If you are confused about the new education policy that has come, and wonder whether board exams will happen or not, let me tell you that these new rules under the policy will take some time to get implemented. And, it is said that practical and applicative knowledge will be given more importance so, board exams will be given less importance in that way. But, this does not mean that board exams will get cancelled. So, don't be misled and it is quite sure, that board exams will be there in 2021. However, semester system is thought to be implemented soon.
Hope this helps.
Good luck!
