What is the importance of last year's question papers and sample papers, I think successful ex-students of your class can tell you, few of students may think that studying sample papers and last year's question papers is an extra burden, they think class notes and textbooks are sufficient to get excellent marks. I would like to tell you one thing that if you have limited bullets in a gun, you can not secure yourself to win a war against your enemy.It is not the intelligence if you leave this opportunity of studying last year's question papers and sample papers in getting excellent marks in your exams. If you want to give your hundred percent in the exams then it is mandatory to go through the previous years' question papers and sample papers as many as you can. CBSE never changes its pattern of question papers at randomly,so if you study last years question papers and sample papers continuously you can get a jump of 10 to 15 % marks in your aggregate %, as compared to the marks you obtain after the study of class notes and textbooks only.
