- Expert Review:
The difficulty level of the paper can be classified as moderate. Section A had easy-to-moderate questions that tested the students for their basic knowledge and understanding of concepts. Section B was moderate and followed the given paper pattern. It had questions on familiar topics which the students should not face many difficulties with. It wasn’t a lengthy paper to say, but if students spent more than half an hour in Section A, they will certainly feel its crunch in Section B.
