Hello Aspirant,
Few days back CBSE did announce the cancellation of class 10th examinations and postponement of class 12th examinations till further notice and they also announced the deadline of result declaration of class 10th candidates on the basis of their internal assessment by June 15th 2021.
For class 12th examinations, new dates will be announced in the first week of July and till then don't break the flow of your preparations because till now there is no announcement regarding conduction of class 12th examinations and also there is no date for result declaration of class 12th.
You can check out the announced results from the official website of CBSE as given below :-
