I think you are asking about the WBCHSE class 12 exam in 2022. Till now the dates aren't announced but if the condition is good then you can expect the examination tentatively from 15th March,2022. For 2021 the examination was scheduled to be from 15 June,2021 but was cancelled due to the increasing caseload of the covid 19. SO everything is condition dependent but you should prepare yourself keep in mind the march deadlines.
