Hello Candidate,

If you are asking that, which sample papers from these two would be best for CBSE Board exam 2021 , then let me clear you first that, both the sample papers are good. Both contains relevant topics and questions as per the syllabus. But Arihant Sanple Papers are somewhat better than the Oswal sample papers . You will find some good quality questions in Arihant sample papers, whereas you will not find them in Oswal.

Hope it helps .
