Hi Aspirant,

You can easily find the question bank on the official website of CBSE for sample papers or previous year question papers,you can also buy the question bank from the store near you.I will suggest you to buy the latest one and with the chapter wise question or if you are getting the topic wise that will be very good.

Hope this will help,please feel free to ask if you have any further queries.

Thank You.
