Question

what is the major difference between the questions of all the three sets of cbse board paper ?????

Answer 1

The major differences between the 3 sets is that:

1) Questions are interchanged.

2) Some questions may be changed (for eg., numbers may change in maths)

Answer 2

CBSE board examination papers are often made in three sets distributed evenly to the students.

Each set is different from one another, often named as set A, B and C.

The major difference between the three sets is the order of questions asked.

Even if the questions are same, their order is changed so that a student cannot ask answer from a friend sitting next to him or her.
