Dear Student,

You can get solved ten year for Class 12th from the book stores online or offline near your place. Or you can purchase solved ten year book online from websites like Amazon, Flipkart etc.

Also, you can visit the official website of CBSE, there you can get previous year Question papers too. And some sample papers for preparation too.

Or you can visit the link to directly download the previous year exam papers for Class 12th-

Hope this helped.

All the Best!!
