Share of each year’s questions
SteadyIn the latest 3 years it was 11.1% of the questions, against 10.6% before that.
How to read this: it counts the questions each chapter had in each previous year paper of IIT JAM Mathematical Statistics; mock tests are not included. A question repeated in the same year is counted, because it was asked. When a year had two papers, their questions are added together and every share is measured against all of that year’s questions.
Practise what is asked the most
Every chapter above has its own chapter-wise test, built from the real previous year questions.
