One of my friends studied at Jamia Millia Islamia (JMI). According to him, getting previous year’s solved papers for B.Sc. Math Honours is easy.

• You can visit the official site of the institute and search for the previous year’s paper.
• Download the question paper year wise
• Click on the link and the paper will be downloaded in Pdf format.

If you do not get them online, try searching for the question books of every year in bookstores or in shopping sites like Amazon or Flipkart.
