hello adil

well certainly previous years questions need not necessarily repeat every year and you should go through previous year questions after youhave completed the whole syllabus and just to see how the exam paper pattern and your knowledge for the subject.

Hii Adil,

Previous year questions should be referred to when you think you are completely done with your preparation. Previous year papers help you gauge and boost your confidence level with regard to the D-DAY. Merely doing previous year papers is not going to serve any purpose. It might give an idea about the level and the pattern of the paper but definelty not a better score.

Hope it helps,

Thanks.
