Hello Aspirant,
See as of now we cannot predict anything about class 12th board examination because these exams have been already postponed till further notice and till now there is no any further decision regarding the new dates or any cancellation so we have to wait till June because in the month of June some decision is expected on CBSE class 12th board examinations.
Don't worry for marking because if the exams will be cancelled then some altrnative would be given as given for class 10th that if any candidate is unsatisfied with his/her result then he/she can appear for an examination which will be conducted when the situations become normal so like this any alternative can be introduced for class 12th as well but till now there is no any notice regarding any cancellation or further postponement of class 12th board examinations.
You can get the latest updates about CBSE examinations from the official website given below :-

I hope this information helps you.
Good Luck!!
