HELLO SANDIPAN

If this question regarding JEE MAIN Shifts and session . There is nothing much difference

For eg
In JANUARY session you will be having like shifts 1st shift,2nd shift
same goes with the april session

HOPE IT HELPS!!

If you are talking in respect of Exams conducted by NTA , then there is no difference between session and shift . Session and shift both refers to the morning and evening shift of a exam on a particular day .

But if you are asking about from another reference, then you should mention it so that you can get your answer according to that.
