JAM Question: The IIT JAM question paper is very important for the JAM aspirant. The JAM question Paper PDF from the year 2016 to 2021 is available on this page. You can download the PDFs from this page. From the year 2021, a new paper Economics (EN) is added and the purview of JAM is extended to social sciences to provide admissions to Masters Programmes in Economics at the IITs. for more details about JAM Question, keep reading this article.
JAM Examination is conducted in seven subjects, also referred to as Test Papers; Biotechnology (BT), Chemistry (CY), Economics (EN), Geology (GG), Mathematics (MA), Mathematical Statistics (MS), and Physics (PH). Previous year question paper is the mirror of the exam. Practicing the previous year question paper, the candidate can enhance their preparation. There is a chance of repeating the previous year’s question in the current year. So, the candidate must go through the JAM Question Papers before the exam.
