Greetings,

1) as of now there is no news of application of the new pattern from this session onwards (though it had been proposed) so rest assured because even if the pattern is introduced, it will be new and anxiety inducing for all equally and the schools will definitely try their best in explaining the implications.

2) The decision to reopen colleges and universities has been left on respective state governments' discretion so keep an eye out for any such news in your state.

3) and 4) both of these are dependent upon whether some new pattern will be introduced or not. For now just carry on with the mindset that board exams will happen at least for this coming session (given the covid circumstances and all).

best of luck!
