Hi there,

As cases of new variant of Corona is increasing while in some state it is decreasing. So it is very uncertain to say that exams of class 8th will be conducted in offline or online mode.

It also depends on state in which your school is situated. If government of your state does not allow reopening of schools then your exam will be conducted in online mode but if government allows reopening of school then your exam will be conducted in offline mode.

Well you should prepare for exam whether it is conducted in online or offline mode.

Hope it helps you

Good luck!
