Yes, very helpful......
We can decide how to frame the answer in a good manner, we can think on those which we dont know.
IF it is problamatic paper (accounts, costing , taxation , FM ) case - we can made rough calculations in mind or with calculator even we didnt put or pen or pencil on paper.
If it is theory case - we can think over case laws and what might be the answer and how to give the presentation overthere.
But what the question how time is utilised depends on the student...........
Overall very helpfulll..........
