Hey!

Since you haven't mentioned which board sample papers you require, I have provided the link to download CBSE sample papers. From the link provided below, you will go the page and when you scroll down you will find option to click to download various subject papers. You can download those subjects which you have. If in case you belong to some other board, then you can mention it in the comment section.
