Hello,
There are separate books available for different topics in JAM Mathematical Statistics. So, buying these books separately for each topic is not a good idea. I would suggest you to take help from study materials which covers the syllabus for all the topics in a single book. So, you don't have to carry 1015 books with you. You can buy Eduncle IIT JAM Study Materials for your exam preparation. They provide the best study materials for IIT JAM preparation. Click here:
