Hello sharon,

For any kind of competitive exam, previous years question papers are must. These questions guides you to prepare in the right direction. And chances of repeating questions are almost 90%, I am not saying all questions asked in the examination are repeated but the pattern, wieghtage or the type of question might be same.

You should go through the last year sample papers for sure as they are the key for good exam prepration.

Best of luck for your upcoming examinations!!
