Hey,

To be very honest same slit itself satisfies the condition of same question for all students. As if they will provide different set of question to different students they can face the objection that particular paper was difficult than the rest.

So in order to maintain the uniformity they keep the question papers same for all the students.

They shuffle the question in each question paper and that makes it difficult for students to cheat. The shuffling helps them in conducting the exam easily and uniformly.

So don't worry the questions will be the same only their order will be different.

Hope that helps.

Thank you.
