Hello Shreya,

I dont think its difficult to acces the previos years papers.the questions are based on the course wise. Each previous year question paper also provides detailed solution in pdf file.

there are number of websites which gives previous question paper.

One site you can rely is https://sample-papers.com/bharati-vidyapeeth-pune/papers .

And dfinetly practising on previous paper will help you in socre good.

Best wishes!!!
