Preparing for IIT JAM Mathematical Statistics (MS) 2026 requires not just knowing the topics but also understanding how much weightage each chapter carries to ace in IIT JAM 2026 exam. Calculus, Linear Algebra, and Probability frequently contribute the most questions on the test, which is equally split between mathematics and statistics.

According to trends from the previous year, mathematics makes up roughly 45–50% of the paper, while statistics also makes up 45–50%. Topics like hypothesis testing, estimation, and probability distributions are heavily tested. Because of this, chapter-wise weighting is essential for creating a well-thought-out preparation strategy, allowing candidates to concentrate more on high-scoring topics without sacrificing the fundamentals.
