Hello Aspirant ,

You should prepare aggressively for your class 12 examination ,you  should spend most of your time for preparation of class 12 exams and occasionally prepare for NCC exam (4-5 hours in a week ) as this exam is not very hard and most of the questions can be easily solved with basic preparation and knowledge  so solving previous year questions can easily get you good enough marks .

As of now their is  no information if the class 12 term 2 exam will be  canceled/postponed or not  so I think it will be conducted as per schedule and you should start  preparing  for it .

Hope this helps.
