Hi student,

Yes, previous year question papers of any examination are definitely helpful in preparation of the examination as well as qualifying it. Solving previous year question papers with honesty improves our speed and accuracy as well as helps us know the pattern of question paper and types of questions asked better. Sometimes questions are even repeated, so it is scoring if you have already solved that question. So it is advisable to solve all previous year question papers.

Hope it helps.

Good luck.
