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!!
