Have a question related to Odisha CHSE ?

Hello Aspirant,

Yes it is possible that examination of any particular subject of all the 3 streams can be conducted on the same day, this is because no candidate would be studying more than 1 stream at once so he/she can easily appear for subject of his/her stream.

See Council of Higher Secondary Education (CHSE), Odisha has not yet released the dates for class 12th examination neither that of practical nor of theory so at this point of time it is highly unpredictable when the exams will be conducted, another reason is that theory exams are expected to be commenced from March mid but till now no schedule has been released by Council of Higher Secondary Education (CHSE), Odisha. Usually practical exams are conducted prior to the theory examinations but same reason applied for practicals as well, no schedule has been released yet.

I hope this information helps you.

Good Luck!!


As of now the council of higher secondary examination, odisha which is the conducting authority for class 12th exams hasn't yet released the examination schedule officially,  generally the exams are conducted in the month of March, practical exams are conducted before the theory exam, the official schedule for the exams may get released this month, but it's an expected date only  to know the exact details you may stay updated at the official website at, or you may also follow our page at to know the latest information for the same,
