Hi there,

I think you have forget to mention the examination name about which you are asking about.

See, mathematics is a subject which only requires practise, practise and practise. If you just solve the previous year questions without knowing about the strategy and basic logic of which you are preparing for so you can get good marks.

See, the concept will remain same but for making it strong you are required to do some practise as well. Definitely you can solve as many question papers you want but it is not sure that you can make it to 60 marks since nobody knows what level of questions sill be asked in the examination.

So first prepare the subjects and then refer to question papers of previous years.

Also, donot depend upon the question papers only, solve on your own first!

Thank you and very good luck:)
